mfileread

This function separately returns the code part and the comment part of an m-file

This function reads a Matlab m-file, trims the content (removing empty lines and unnecessary spaces), and divides the content into code and comment part.
It returns a struct with fields holding information on the number of non-empty lines, and three strings representing the whole text, the code part, and the comment part.

This function can be used to access and analyze code and comments seperately.
It could e.g. also be used to generate a trimmed copy of an m-file with all comments removed by entering

mfinfo = mfileread(fname);
fid = fopen(fname2, 'wt');
fprintf(fid,'%s',mfinfo.code);
fclose(fid)
