N = 500;
A = zeros(N);
A(20:50, 75:100) = 6;
for i = 1:10
A = alter(A);
figure(1);
imagesc(A);
pause
end
When I run this, it shows me an error Undefined function or variable 'alter'.

which -all alter
'alter' not found.
What function are you trying to call?
From the tag can I assume you're trying to use Computer Vision Toolbox? Looking at the list of functions in that toolbox I don't see one named alter.

I searched all of the .m files for all of the toolboxes that I have (I have most but not all). I was not able to find any function named alter or any class method named alter
