Please implement the following function gradient_magnitude using Sobel Masks in Matlab.

b) Write the function gradient magnitude that takes one input: a grayscale image (a matrix, not a filename). This function should return an image (a matrix, not a file) of type double with the same dimensions as the input. This output contains the magnitude of the gradient. You should compute the gradient using the Sobel masks shown in figure 10.14 (both editions) using your spatial_filter function. b) Write the function gradient magnitude that takes one input: a grayscale image (a matrix, not a filename).
