Zooming
• zoom(M, hscale, vscale)—Returns matrix M resized by factor hscale horizontally and vscale vertically.
Arguments
• M is an image matrix.
• hscale, vscale are positive, nonzero real numbers representing the horizontal and vertical scales for zooming.
Additional Information
• The function returns the scaled image, which is a different size matrix from the input.
• It is recommended to avoid the use of excessively large values for hscale or vscale, because of unreasonable computation times and display problems.
