Problems with using "strmatch" in Matlab 2012a GUI

Hi, I get an error message when I try to use "strmatch"

>> At compilation, "strmatch" was determined to be a variable and this variable is uninitialized. "strmatch" is also a function name and previous versions of MATLAB would have called the function. However, MATLAB 7 forbids the use of the same name in the same context as both a function and a variable.

I tried exactly same code in command window, and everything works fine.

index_trigger = strmatch('TRG',u(index_request,:));

but when I put it into gui, the error happens. I search out my code in my gui.m, and I didn't find anywhere strmatch appears as a variable.

Moreover, it seems this function will be removed from the future release. I really hope not ...

Could someone help me out? Thanks!

Do you happen to have a strmatch() on the left side of an "=" ? I have seen some people put it there in an attempt to assign to a substring of a string.

Thank you Walter for your reminding. I checked several times, and finally found that I put a bracket right after my first index at one place. So, this is not a technical issue. Never mind. Thanks again.
