From: teki on 10 Aug 2010 13:23 Hi, I am facing the same problem today. I try to run the .m file in my current directory and Matlab would give the message - "Undefined function or variable". I add the current path and still it does not recognize any .m file in the current directory. Moreover, any new .m file is not running at all, while some of the old .m files I executed previously are working fine. Any help is most appreciated!

From: Shanmugam Kannappan on 10 Aug 2010 13:38 Hi, May I know how you are trying to run the file? I mean,r u running in the command window or directly from the m-file. Also,please check your function name's & variables names are not the same. Shan!

From: teki on 10 Aug 2010 15:34 Hi Shan, I tried running the file from both the command window and directly from the m-file but neither works. The function and variable names are not conflicting. The same function works fine on my pc (with r2008a), but not on my laptop running matlab r2009a. Even a simple m-file to display a message won't run on my laptop now. On some other pages, someone suggested it might be a problem with the pathdef.m file, but I am not sure...I even added the path of the current directory before running the m-file, but to no avail!

From: Jan Simon on 10 Aug 2010 16:27 Dear teki, it would be helpful, if you give us a complete description of what has happened: 1. Did Matlab work fine before? 2. What has happened in between? 3. Does "path" reply the expected toolbox folders? 4. Do you have read access to these folders? 5. Does WHICH find any of the toolbox functions? 6. Are you sure that there are no naming conflicts? If so, why? 7. Does Matlab provide any error messages, if yes, please post them. 8. Further ideas of what might be helpful to identify the problem? Kind regards, Jan

Hi Jan, Thanks for your reply. In response to your questions; 1. Matlab worked fine before 2. I discovered this problem four days ago. I had to go back to my desktop to run this function. Today, it worked once when I copied the file from my pc, and saved the file with a different file name on my laptop. I thought that was it, but on subsequent attempts, the m-file would not run. 3. Yes 4. Yes 5. Yes 6. I am quite positive about that. I don't understand why the same m-file runs without any error on my desktop but fails completely on my laptop. 7. Error reads - "undefined function or variable". 8. I am not sure what else can I say about this.
