how to connect comsol to matlab.

Hi. My comsol version is 3.5a and matlab is R2012a.

I made a M-file through comsol. And I tried to open it in matlab.
But it didnt work. So i wonder what the problem is.

When i ran m-file in matlab i showed this message.

>> comsol
Undefined function 'flclear' for input arguments of type 'char'.

Error in comsol (line 4)
flclear fem

>>

I don't know the reason. But i think i have to make something about program in M-file, right??

If you know how to do in this case, let me know.

Thanks.
