Setting up MATLAB contexts

If you are forced to use MATLAB (here’s a whole blog devoted to the topic of why not to use it http://abandonmatlab.wordpress.com/) the following advice maybe useful for easily managing your path and hence creating contexts of work.

In cases where Administrator privileges are not held, the following config. is flexible.

Define MATLAB’s userpath to be a user writeable directory. This is the initial directory MATLAB will parse.

Within the userpath create startup.m:

if ~isdeployed
    path(my_path)
    set_vars

Where my_path is a matlab file which sets the path like:

function p = my_path
     p = ['/home/chris/matlab;', '/home/chris/important;'];
     cd('/home/chris/matlab');
end

So we set the path and cd to a relevant directory. Also in the userpath folder, one can keep many files like my_path.m, which define different contexts to work in, making changing contexts as easy as:

path(my_other_path)

Whithin each context path file if you also call the set_vars script, this allows set_vars to contain useful variables e.g. paths to output directories and the like.
