## This PKGBUILD installs dependencies, provides desktop icons, and patches a
## currently installed version MATLAB.  It should be installed after a manual
## install of MATLAB and will find the location where MATLAB is installed as
## assuming the executable is on the PATH.  This package should not be used with
## the AUR matlab package by Daniel Shub and Ido Rosen.

## The version of this package will always match the MATLAB ## version numbers
## (of which you can find here
## https://en.wikipedia.org/wiki/MATLAB#Release_history) for which this package
## is intended to support.  Please flag as our of date upon a new MATLAB
## release.

## MATLAB is a commercial product with a paid license, this package does not
## provide MATLAB, it only provides dependencies and fixes to make it run better
## on Arch Linux.

## Much thanks to Daniel Shub and Ido Rosen whose matlab PKGBUILD served as a
## guide when making this one.
