What did you expect to happen? What happened instead?
I expected to get some sub matrix and get the median array of the sub matrix.
For matrix of smaller size, it works fine.

I'm using matlabcontrol 4.0.0, Matlab r2010a on Debian Squeeze.
I'm using MatlabControl from outside MATLAB. The client class is a class
running inside a Tomcat 6.0 (the one in the Debian repository!).
At the attempt of calling the MATLAB instance, no error is catched, but the
connection time out!
This problem happens only if Tomcat is running as a service. If Tomcat is
launched from the shell everything works fine.
Thinking it was a security problem, I tried to grant all security permissions
to the web application but nothing changed.
I thought it could be related to the PATH environment variable, but the PATH
variable maps the MATLAB codebase location and nothing good happened.
Files permissions are OK.
Am I forgetting something?
Thanx
Rudy

New facade for existing matlabcontrol code
Implementation of the JSR-223 API
We (CSIRO Marine and Atmospheric Research) are using Matlabcontrol as a JSR-223
bridge to Matlab from our code, this lets us treat Matlab as just another
execution engine like other JVM based languages such as JRuby, Groovy, Jython
(we also use native code based bridges to R and Perl). Implementing the JSR-223
API in Matlabcontrol will ease its adoption into existing systems. We can
contribute the JSR-223 bindings under MIT licence from our nascent TrikeND
(http://sourceforge.net/projects/trikend/) project to be maintained within
Matlabcontrol.

It was working fine when deployed on windows 7. I migrated the project on windows 8.1 which also had another version of matlab installed.I thought , there was error bcoz of multiple versions of Matlab so i uninstalled both and again installed the required one.Still not working ... Please tell me where is the problem and how can i resolve this..

Is this an entirely new feature or an enhancement of an existing feature?
I haven't been able to find a repo distributing compiled jars for this project. This would be a handy thing to have, as it would make listing it as a dependency in projects using maven/lein/gradle etc. easier.
What is the feature or enhancement?
The enhancement would be to upload this project to a repo like Central (http://central.sonatype.org/). This would make it easier for other projects to make use of matlabcontrol as a dependency, by listing the library in their build scripts for maven, ant, etc to download.
If you have currently implemented a solution of your own to implement this
feature or enhancement, how have you done so?
I haven't done anything on this. As I understand, sonatype will provide free hosting in their repo for open source projects, but there's a somewhat long-winded approach involved in getting this done -- see http://central.sonatype.org/pages/ossrh-guide.html

What steps will reproduce the problem?
1. Run the following sample code:
MatlabProxyFactory factory = new MatlabProxyFactory();
MatlabProxy proxy = factory.getProxy();
proxy.eval("disp('hello world')");
// Use the proxy as desired
System.out .println("disconnected: " + proxy.disconnect());
What did you expect to happen? What happened instead?
I would expect disconnect to print as true based on the javadoc.. but it prints
as false.
If there was a stack trace, please copy it here.
Please provide any additional information below.
It looks like RemoteMatlabProxy#disconnect() returns #isConnected(), which is
the reverse of what the javadoc suggests.
I am not sure if there are any other implications of this flag being flipped.

This can be avoided by altering the port used when the RMI registry is created,
so as to ensure the port is unique to the running process.

Just wanted to contribute back some changes that I made:
https://github.com/diffplug/matlabcontrol
Added CopyPasteCallback to the set of options for creating a
MatlabProxyFactory. The factory sends a chunk of code to the callback, and the
user copy-pastes this code into a MATLAB terminal to initiate a connection.
ThrowableWrapper now initializes the getMessage() field with MATLAB's raw error
text.
Added OSGiClassloaderFriendly to the set of factory options. When this flag is
set to true, RMI is started in a way that doesn't get hosed by OSGi.
The CopyPasteCallback is very handy for implementing interactive applications
such as this:

Following the documentation I first tried:
MatlabProxyFactoryOptions options = new MatlabProxyFactoryOptions.Builder()
options.build();
options.setHidden(true);
The error is: type mismatch and if the type of options is changed to builder:
Builder options = new MatlabProxyFactoryOptions.Builder();
options.build();
options.setHidden(true);
There are no errors, however none of this options takes into effect.
Then I tried:
MatlabProxyFactoryOptions.Builder options = new
MatlabProxyFactoryOptions.Builder();
options.build();
options.setHidden(true);
no errors but matlab does not run hidden again

What version of matlabcontrol are you using?
4.0.0
What version of MATLAB are you using?
R2012a
What operating system are you using?
Windows 7
Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside MATLAB. Specifically, from a custom-written Java plugin in the
Java-based microscopy software MicroManager.
What steps will reproduce the problem?
1. Creating a MatlabProxyFactoryOptions instance.
What did you expect to happen? What happened instead?
I expected Matlab would open, create an instance, and then I would later be
able to connect to that instance. When I create an instance, I get the error
message below in Matlab. Commands sent through the proxy will execute, but I
cannot reconnect to the session.
Errors:

Are you using matlabcontrol from inside MATLAB or outside MATLAB? Outside
What steps will reproduce the problem?
1.In the Builder, set setHidden to true and use setMatlabStartingDirectory to
set a starting folder.
What did you expect to happen? What happened instead? I expected a minimized
command window opened in the starting folder I specified. However, the
minimized command opened at the location where the Matlab executable was
present. Hence, it was unable to execute a Matlab script present in the
location specified by me as it never opened in that location. As a workaround,
I manually pass a 'cd' command to the proxy to switch to the desired folder and
then execute the script.

2011a 64-bit
What operating system are you using?
Windows 7 64-bit
Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside in a Java application
What steps will reproduce the problem?
1. Run this code:
MatlabProxyFactoryOptions MATLABOptions = new
MatlabProxyFactoryOptions.Builder().setHidden(true).build();
MatlabProxyFactory factory = new MatlabProxyFactory(MATLABOptions);
MatlabProxy proxy = null;
MatlabTypeConverter converter = null;
try

proxy.eval("a = [1+1i;2+2i;3+3i];");
double[][] arrayRealValues = converter.getNumericArray("a").getRealArray2D();
double[][] arrayImagValues = converter.getNumericArray("a").getImaginaryArray2D();
}
catch (Exception e)
{
System.err.println(e);
}
What did you expect to happen? What happened instead?
Expected to be able to access the variable in matlab without throwing an
exception. The following message/exception was displayed instead:
"matlabcontrol.MatlabInvocationException: RuntimeException occurred in
MatlabThreadCallable, see cause for more information"
The cause was indicated as: "java.lang.ClassCastException: [Ljava.lang.Object;
cannot be cast to [D"
Please provide any additional information below.
Note that the above program works perfectly if accessing a real valued
variable, i.e. if the eval line was adjusted to "proxy.eval("a = [1;2;3];");",
and the getImaginaryArray2D command was removed.

I expect to open Matlab only one time but according to comments here, changing
the code bellow would fix the problem:
MatlabProxyFactoryOptions options = new
MatlabProxyFactoryOptions.Builder().setUsePreviouslyControlledSession(true).buil
d();
I changed but when java is run, a new matlab window is opened.

What did you expect to happen? What happened instead?
Please provide any additional information below.
Sometimes matlabproxy.eval(cmd) runs the command inside a method namespace
instead of the main namespace. This happens in a gui matlab application, and
I'm guessing it's related to callback functions. I expected this to not be
possible due to matlab's single-threading, but I can see it happen occasionally.
Anyway: Replacing "eval" with "evalin","base" in the three relevant functions
of JMIWrapper.MatlabThreadOperations seems to fix it.

Enhancement of existing feature,
What is the feature or enhancement?
I want an option added to change the architecture. Right now when I try to
start matlab through the proxy it fails to start because the default arch is
64-bit because I have 10.6.8, but matlab is MATLAB_R2010aSV, which has no
32-bit mac version. The only way I've found to launch it is using this script
and pointing the proxy towards it:
matlab.sh:
#!/bin/bash

I don't say the script is perfect. It might be dropping an argument, but that
should give you an idea of what I mean.
If you have currently implemented a solution of your own to implement this
feature or enhancement, how have you done so?
I could probably do this if I needed to, though I don't see any build scripts,
project files, or hints on how to build it, which would be a little annoying to
do. Or does this need something from MATLAB to build?

matlabcontrol-4.1.0.jar
MATLAB R2014a
Win 7
Using matlabcontrol from outside MATLAB!
Steps that should reproduce the problem:
1. sign code (with code signing cerificate) and copy onto web-server
2. launch app using Java Web-Start
The location of "matlabcontrol-4.1.0.jar" was determined as being on the
C-drive; however, it is in fact on the web-server.
Error Message:
Support code loaction was determined improperly. Location does not exist.
Location determined as: C:\apps\jet\beta\matlabcontrol-4.1.0.jar

What version of matlabcontrol are you using?
(Release versions: 4.1.0, 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)
4.1.0
What version of MATLAB are you using?
R2011a
What operating system are you using?
Windows 7
Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside Matlab (inside Java)
What steps will reproduce the problem?
1. Create Matlab script which writes something to file using print, save, or
saveas.
2. Run Matlab script from Java.
3. Matlab script appears to execute in its entirety, but nothing is written to
file.
What did you expect to happen? What happened instead?
I expected something to be written to file and to appear in my home Matlab
directory. This is what happened when running the script from Matlab itself.
