hey everyone i have 2d matrix which i have repeated 24 time using repmat function. i need to rotate each of these repeated matrices by 7.5degrees. ie 1st matrix rotated 0deg, 2nd matrix rotated 7.5deg, third matrix rotated 15deg and so on... any suggestions?

Use a for-loop over the pages and imrotate
Something like:
X = your_original_2d_image
Xrot = zeros([size(X) 24],'like',X);
for ii = 1:24
Xrot(:,:,ii) = imrotate(X,7.5*ii,'crop')
end
