depends.m

%DEPENDS Computes dependencies for a given function, f.
%
%   c = depends(f[,'mfile'])
%
%   Inputs:
%   f        string, name of function or path to function
%   'mfile'  list .m files instead of .p files
%
%   Outputs:
%   c        cell array of paths to dependencies
%
%   Example:
%
%   % Get dependencies and zip into a file
%   c = depends('myfun');
%   zip('myfun.zip',c);
%
%   % Get dependencies and extract just file base names and print
%   c = depends('myfun');
%   n = regexprep(c,['^.*\' filesep],'')
%   fprintf('myfun depends on:\n');
%   fprintf(' %s\n',n{:})
