arrays in loops, changing variable names (i.e. A{1}, A{2}, ...)

I'm trying to use arrays to store information in a different variable with each iteration in a for-loop.

I used A{i}=edge(BW,'canny'); inside the loop (using curly brackets as the information is a matrix)

However, once I run the program, matlab does not return a A{1} or A{2} (and so on), but A{i} does exist. Any advice on what I've done wrong?

I don't see any problem in your code, look at this example

for k=1:3
  BW=rand(50);
  s{k} = edge(BW,'canny');
end
celldisp(s)

please see my comment underneath the question. My program does not return values for A{1} or any other value of i

If your matrices have different sizes, it is not a problem

for k=1:3
   N=10+k
   BW=rand(N);
   s{k} = edge(BW,'canny');
end
s{1}
s{2}

To make your question clear, please post your code
