well... this is NOT what you told CSSM in your OP - and explains the behavior
- you access the newly created file before you close/flush it...

Close the file... :)

Note that if you're editing m-files and execute a given function that
Matlab caches so you'll want to do a

clear yourupdatedfunction

to ensure you get the modified version as well.

_before_ opening and reading the new file.

Thanks, I'm clearing the functions now and it seems to be working.

Dear Adam!

> fid2=fopen('feval.m','w');

Be careful! If there is no file called "feval.m" in the current directory, you overwrite FEVAL.M of Matlab's toolbox. Beside this, it is not a good idea to re-use names used by Matlab functions, because the shadowing usually results in problems which are hard to debug.

Calling automatically created M-files is inefficient in Matlab, because parsing a function needs a lot of overhead time. If the new function is called repeatedly afterwards, this timing problem gets smaller. Anyhow, I'd avoid this technique whenever it is possible. Search in this newsgroup for "evil eval" to learn more about the possible dangers.

Good luck, Jan
