How to save multiple matrices in each iteration of a for loop into a structure?

A = imread('Ish.JPG');
A = im2single(squeeze(mean(A,3)));
A = im2double(A);
[pyrRef,pind] = buildLpyr(A,'auto');
nLevels = 7;
kernelx = [0.0, 0.0, 0.0; 0.5, 0.0, -0.5; 0.0, 0.0, 0.0];
kernely = [0.0, 0.5, 0.0; 0.0, 0.0, 0.0; 0.0, -0.5, 0.0];
for k = 1:nLevels
subband = pyrBand(pyrRef, pind, k);
rx(k) = conv2(subband(k),kernelx);
ry(k) = conv2(subband(k),kernely);
end
Here, for each 'k' (k = 1:7) there will be 3 matrices (subband, rx, ry). So, I want to save this in a structure of diemnsion (7 X 3). How do I do that within this loop?

clear S
for k = nLevels:-1:1
S(k).subband = pyrBand(pyrRef, pind, k);
S(k).rx = conv2(subband(k),kernelx);
S(k).ry = conv2(subband(k),kernely);
end
