Thread Subject: rmpath problem

I want to remove the path C:\temp\ whitin a script

rmpath(' C:\temp\') obvious works fine. However when I run the script for a second time (or when path is already removed) I get the following warning:

Warning: "C:\temp\'" not found in path.

Can this be solved? E.g. can I check if a directory is in the "search path"

Either wrap it in a try
try
  rmpath(folder);
catch
end

or check existence beforehand:
if exist(folder, 'dir')
  rmpath(folder);
end

rmpath removes the folder from Matlab search path but does not delete the path itself. So check with EXIST is not consistent. Rather use PATH command.

It is only a warning, not an error. This might be instructive:

addpath('c:\temp')
rmpath('c:\temp')
rmpath('c:\temp')
% Warning: "c:\temp;" not found in path.
% > In rmpath at 58
warning('off','MATLAB:rmpath:DirNotFound')
rmpath('c:\temp')
warning('on','MATLAB:rmpath:DirNotFound')
rmpath('c:\temp')
% Warning: "c:\temp;" not found in path.
% > In rmpath at 58

You're right Bruno - I had incorrectly assumed he was deleting the
folder from the hard drive rather than just getting rid of it from the
search path.

Dear Koos!

PathCell = strread(path, '%s', 'delimiter', pathsep);
if any(strcmpi(PathCell, 'C:\temp'))
  rmpath('C:\temp');
end

Consider that the path has not trailing file separator.

Kind regards, Jan
