Error while evaluating UIControl Callback

Best Answer

You could get this error if im_n is a matrix that does not have im_sz(2) number of columns.

Nazil - the problem is with your function signature

function [IC]=f_SegmentasiHU(img1.IMA);

Note how you are defining the (only) input parameter as img1.IMA using the period '.' which is invalid given the context. Try just using

function [IC]=f_SegmentasiHU(img1)

instead (note that I've removed the semi-colon from the end of the line too - there shouldn't be any need for it).

MATLAB: Storing multiple value in array without overriding.

"How to avoid that?"

Simply by changing the Excel worksheet name on each iteration of the outer loop, e.g.:

...
for z=1:nfiles
     ...
     F = sprintf('output_%d.xlsx',z);
     xlswrite(F,...); 
end

Or you could use fileparts to create a name based on the original image filenames, e.g.:

[~,N] = fileparts(thisname);
F = sprintf('%s.xlsx',N);

Note that you should place the xlswrite inside the try section, otherwise your code will export the results from the last imported file, without any warning. Placing so much code inside try is not a good idea, as this hides any errors and bugs in that part of the code. Better code would simply use exist to test for the file (rather than try). I doubt that try does anything useful here anyway, as dir only lists existing files anyway, so most likely you should get rid of try entirely.
