Hello,
I have matrix A:
A =
1 2
3 4
and want to resize it to be matrix B. Matrix B should be like this:
B =
1 1 1 2 2 2
1 1 1 2 2 2
1 1 1 2 2 2
3 3 3 4 4 4
3 3 3 4 4 4
3 3 3 4 4 4
My method is an ugly one like this:
A = [1 2;3 4];
scale = 3;
B = [];
[M N] = size(A);
for i = 1:M
for j = 1:N
B((((i-1)*scale)+1):(i*scale),(((j-1)*scale)+1):(j*scale)) = A(i,j);
end
end
So, how can I resize or scale matrix up without using for loop?
Thanks for advice,
K. Pituso
