Is it possible that these directories you are using are underneath one of the Matlab installation directories? If so that can cause a lot of problems.

If that doesn't work, have you called tech support? Either of these seems preferable to re-installation. After some testing I will add some information. First, I was able to run restoredefaultpaths from a DOS window but the problem remains. Second, although I can't run any functions from the current directory I can use help <fucntionName> to access the help information I put at the start of each file. This was also the case when I encountered the 5-file limit for anything along the added search path: I could access help information from any file but couldn't call the function from either the command line or within a script. Next: to try the rehash suggestion that arrived as I was writing this...

If so that can cause a lot of problems. I checked the PATH statement and there are now only the paths to the toolboxes. Previously they were at the top of the search list (first to be searched). Just tried rehash and no change. One thought that has come to mind: The specific error I am receiving is as follows: __________________________ ??? Undefined function or variable 'curvatureDetection'. __________________________ Could Matlab be halting the search when it discovers there is no variable by this name and not proceeding the the usual next step of checking the current directory? Consider, if I bypass the local variable search by using run to process the script, I receive this error: ____________________________ run curvatureDetection ??? Error using ==> run Error using ==> evalin Undefined function or variable 'curvatureDetection'. _____________________________ I'm not yet sure if this yields any new insight.

Something seriously went wrong. RESTOREDEFAULTPATH is thought as an emergency tool, which run even under very strange conditions. Actually the exectuted command should include the perl.exe in double quotes also. I'd decide for a re-installation of Matlab. Jan |
