S and temp don't have the same number of rows. In fact, S was never even defined before you tried to use it, or at least if it was, you didn't show that code.

Do not use eval!
str = fullfile('C:\Users\Dhanya Francis\Desktop\Project\', sprintf('%d.jpg', i));
img = imread(str);
Your line
is incorrect for any RGB image, and .jpg are almost always RGB images.
[d1,d2,d3,...,dn] = size(X), for n > 1, returns the sizes of the dimensions of the array X in the variables d1,d2,d3,...,dn, provided the number of output arguments n equals ndims(X). If n does not equal ndims(X), the following exceptions hold:
n < ndims(X) di equals the size of the ith dimension of X for 0<i<n, but dn equals the product of the sizes of the remaining dimensions of X, that is, dimensions n through ndims(X).
