Searching for a directory in matlab Path

Hi, I want to find out if a particular directory name exists in the matlab path. This I can do easily with exist('dirname','dir') If the directory now exists, then I wish to find its complete path from the Matlab PathList. Could someone help me out with this.

Thanks.

I don't fully understand how exist('dirname','dir') works. If you need to find out the full path, I recommend the following code which tries to find the folder 'simulink'.

use regexpi() to replace strfind() if want to ignore the case, but then also need to take care of the backlash '\'. Maybe should just use

Ind=strfind(lower(PathStr),lower([filesep,'dirname']))

PathStr=regexp(path,pathsep,'split');
Ind=strfind(PathStr,[filesep,'simulink']);
Ind=cellfun('isempty',Ind);
FoundPath=PathStr(~Ind)

If exist(myDir,'dir')==7 I usually go to the MATLAB root and do a system find, but remember this can return several values based on all the directories with the name myDir on the path

cd(matlabroot)  
!find . -name myDir

Another way to run system commands in MATLAB is

[status,cmdout] = system(cmd,'echo') % where cmd='find . -name myDir &'
