Matlab dir emulation function
Matlab and Scilab dir behave differently:
The function mtlb_dir([path]) is used by mfile2sci to replace dir([path]) when output is stored in a variable. There is no replacement possibility for it, else (when mtlb_dir is replaced by dir) data can not be extracted like in Matlab. For example, Scilab equivalent for Matlab L=dir;file_name=L(1).name; is L=dir();file_name=L.name(1);.
Caution: mtlb_dir has not to be used for hand coded functions.
