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.
Many thanks, Sundeep
