Subscripted assignment dimension mismatch.

Error in guiast>pushbutton6_Callback (line 528) C(rowspan,colspan,1) = R1;

Error in gui_mainfcn (line 96) feval(varargin{:});

Error while evaluating uicontrol Callback

Here is the code

C(rowspan,colspan,1) = R1;
C(rowspan,colspan,2) = G1;
C(rowspan,colspan,3) = B1;

You do not say how rowspan and colspan are calculated, but the problem is that they do not match the size of R1 (or the other two arrays, probably). The solution depends on what you want. If rowspan and colspan are correct but you do not want the whole of R1, try

C(rowspan,colspan,1) = R1(rowspan, colspan);
% etc

assuming R1 is a 2-D matrix and rowspan and colspan represent a part of it.

If you want the whole of R1 etc. you can use

rowspan = 1:size(R1, 1);
colspan = 1:size(R2, 2);

to get the correct ranges.
