Thread Subject:

directory separator

Hi all

I'm writing a matlab-function that I need to run on both Win-PC's and
UNIX-stations.

My question is:
Is there a matlab-variable, say DIRSEPARATOR, describing the directory
separator ('\' on Win-PC's and '/' on UNIX)?

This would allow me to specify a path something like
strcat(DIRSEPARATOR,'matlab',DIRSEPARATOR,'datafile.txt') which would
act as
'\matlab\datafile.txt' on PC's and as
'/matlab/datafile.txt' on UNIX-systems.

Any help is appreciated

% BTW,
% strcat(DIRSEPARATOR,'matlab',DIRSEPARATOR,'datafile.txt')
% is the same as
% [DIRSEPARATOR 'matlab' DIRSEPARATOR 'datafile.txt']
function z=dirseparator

if isunix
z='/';
else
z='\';
end;

Yes, use filesep

No, use fullfile instead
