Hi, Completely off topic, but just a quick question for any Matlab users. I am using v5.3 and when I create a new .m file (i.e. a new function), I have to close->restart matlab to get it to pick the new function up....otherwise it reports "??? Undefined function or variable..." when I try to call the newly created function. Now, I have the path of the new .m file set up correctly, so matlab knows where the function is - it just seems that it doesnt update what it can see in that directory. Is there a painless way to overcome this/am I doing something stupid or is it just a problem with Matlab/Windows?
