RELFILE(FILE,PATH) converts full filename FILE to a relative filename with respect to PATH.

REL2FULLFILE(RELFILE,PATH) converts relative filename RELFILE to full filename using PATH as the base path.


relfile('C:\Program Files\MATLAB\R2009a\bin\matlab.exe','C:\Program Files\MATLAB\R2009a')

returns '.\bin\matlab.exe' and

rel2fullfile('.\bin\matlab.exe','C:\Program Files\MATLAB\R2009a')

gets the original path back.

relfile('C:\Program Files\MATLAB\R2009a\bin\matlab.exe','C:\Program Files\MATLAB\R2009a\toolbox\matlab')

returns '..\..\bin\matlab.exe' and


expands to 'C:\MATLAB\bin\matlab.exe'
