A banded matrix library for python.

bandmat's Issues

extra compile args -Wno-unused-but-set-variable cannot be used in vc.

cl : Command line error D8021 : invalid numeric argument '/Wno-unused-but-set-variable'

Complex matrices support

Hi,
It appears that complex matrices are not supported. When I do the sum of two banded complex matrices, I get

Buffer dtype mismatch, expected 'float64_t' but got 'complex double'

Here is an example for this problem.

import bandmat as bm
import numpy as np

A = np.zeros((3,4), dtype='complex')
B = np.zeros((3,4), dtype='complex')
Abm = bm.BandMat(1,1, A)
Bbm = bm.BandMat(1,1, B)
Abm+Bbm

'-Wno-unused-but-set-variable' causes error during install

Hi.

I'm currently using Windows 10 with VS2017.
While installing bandmat via pip, '-Wno-unused-but-set-variable' is not recognized by the compiler, causing error during the installation.

Commenting out the part in setup.py seems to alleviate the issue. (though with many warnings)

missing numpy "include_dirs" in setup.py

Hi,
I have done a package for the Gentoo distribution. Doing so, i have been forced to modify setup.py (and test_linalg.py). See the sed lines (line 27,28,29) in the following if you interested in
bandmat-0.5-r1.ebuild.txt

Best regards.

setup fail

It appears that I can't install it with neither pip or setup.py method.So Here comes my case:
I'm using a OS X 10.11.6 System with python 2.7 installed,In case of some side effects I choose to install it within the virtulenv environment.
The error:
bandmat/full.c:237:10: fatal error: 'numpy/arrayobject.h' file not found
#include "numpy/arrayobject.h"
I've got some ideas about that the problem comes up because it can not locate the 'numpy/arrayobject.h' which actually exist at '/include/lib/python2.7/site-packages/numpy/core/include/numpy/arrayobject.h'

test_solve is failing on current Debian testing (buster)

Hi,
I just tried to install bandmat on a current updates Debian testing (buster, as of Nov 15, 2017) with the following commands:

sudo apt-get install python-numpy python-scipy

followed by

virtualenv --system-site-packages env
env/bin/pip install bandmat

which produced

then I tried

Do you have any hint about how to fix the issue? Do you think it is a bug in bandmat or in its dependencies?

Issue with installation

Hi Matt,

I tried installing your module but it would not compile unless I removed the compiler argument '-Wno-unused-but-set-variable'. Thanks for writing this package, it's quite useful!

请问为什么安装bandmat报这个错，我已经把gcc降了
