function y = fcn(u,img1,img2, data)
Ne = u; L = img1; re = img2;
for n=1:Ne [r,c] = find(L==n); % Extract letter n1=re(min(r):max(r),min(c):max(c)); % Resize letter (same size of template) img_r=imresize(n1,[42 24]); end y = img_r;
why y is error?

Why do you think img_r would exist without defining it?

I seem to have misread. Selecting your code and pushing the {}Code button would help with making the code more readable.
You should copy the entire error message.

function y = fcn(L,Ne,re)
for n=1:Ne
[r,c] = find(L==n);
% Extract letter
n1=re(min(r):max(r),min(c):max(c));
% Resize letter (same size of template)
img_r=imresize(n1,[42 24]);
end
y = img_r;
the error message is:Variable 'img_r' is not fully defined on some execution paths.
Function 'MATLAB Function1' (#487.229.234), line 9, column 5: "img_r" Launch diagnostic report.

You should answer in comments, not in answers. The answer section is for solutions to the problem, not for responses to clarification.
You should rethink what you want to do. This code seems to overwrite the result on every iteration. The error you are getting is strange, except if Ne is allowed to be 0.
