Hello...

I defined a MATLAB function in global definitions with argument T
i created function.m file in matlab and saved both .mph and .m file in the same folder..
and i set the matlab path to point the same folder..

when i am trying to execute ..gives the error ' Function is not found'..

Is there any steps i am missing..

i follwed in comsol 4.1.. 1.define MATLAB function and arguments in comsol
2. create .m file in matlab
3. set the matalb working path to the folder where .mph and .m files are saved.

can any one suggest how to make comsol to find the matlab function..

thanks
pavan

True. I have the very same problem. Apparently, everything is following the Livelink Guide, still doesn't work.

Do you get the Comsol error "Function not found.." or "MATLAB function not found.."

The first could also mean that your Matlab function is already known to Comsol but you somehow incorrectly call it. (e.g. no argument)

The latter really indicates that your function is not known to Comsol and its a path issue. (filename=function name ?)


You also have to take care of that Comsol doesnt update your Matlab function if you change your m.file. That kept me busy for a day. check this thread: www.comsol.de/community/forums/general/thread/7946/

Thanks. This thread is a good one. I'll try that. I guess the problem is that I have more than one version of MATLAB, both 32 bits and 64 bits, or something similar to this. I also see both R2010b, and R2011b in the installed folder of MATlAB.
