Functional Tools for Matlab

Functools

Functional programming tools for Matlab. It includes the following subpackages.

• list: list related functions (foldl, foldr, zipWith2, etc)
• curry: higher order functions to change the calling structure of a function. This includes partial, rpartial, and curry.
• util: Some useful utility functions that don't fit elsewhere.

Install

Global installation can be done through the user's MATLAB directory. Place this entire directory in a directory under the userpath location (such as '/home/user/Documents/MATLAB/functools/'). The result will look like so.

Documents\
    MATLAB\
        functools\
            README.md
            +functools\
                +curry\
                    ...
                +list\
                    ...
                +util\
                    ...
                ...

Now, create or edit the function Documents/MATLAB/startup.m (or wherever your startup.m is) to include the following.

disp('Adding functools') % not needed but I like the reminder.
addpath('functools')

Start a new instance of Matlab and the functools package should be ready to use.

Using functools

Functools is defined as a Matlab package, which means the functions inside this package are called a bit differently that normal functions. In order to call the functions, their full namespace must be specified

functools.list.head([1 2 3 4])

or a function can be imported specifically

import functools.list.head
head([1 2 3 4])

or an entire subpackage of functions can be imported.

import functools.list.*
head([1 2 3 4])

If you would like to use the functools functions inside your own function, the same import rules will apply.

function out = add(a, b)
    import functools.list.zipWith2

    out = zipWith2(@plus, a, b);
end
