MATLAB: Reason for this error?

Question

>> i_close =(gi,se2); figure,imshow(i_close);

It's reporting the error=

??? i_close =(gi,se2); figure,imshow(i_close);
              |
Error: Expression or statement is incorrect--possibly unbalanced (, {, or [.

i cant see any reason!!! Help..

Answer 1

   i_close =(gi,se2);

This isn't valid MATLAB. Should there be a function call here, or are you trying to concatenate? Eg

   i_close = functionname(gi,se2);
   i_close = [gi,se2];
