I have a large matrix A of size(m*n*9), now I want to normalize it at
each pixel, so for example
A(1,1,:) = [1 2 3 4 5 6 7 8 9] and I want
normA(1,1,:) = A(1,1,:)/sum(A(1,1,:));
I now use an iteration to do this computation, but it's very slow as
the matrix is large. Is there any other elegant way of doing it?
Also, I want to find out the index of the max value of A. So in the
example above, I want to compute an index matrix ind(1,1) = 7; again,
any clever way of doing this?
