Use the MATLAB imshow() function to load and display the image stored in the provided MATLAB image.mat file (available in the Supporting Materials area). For the loaded image, derive the value of k that will result in a compression ratio of CR = 2. For this value of k, construct the rank-k approximation of the image.I have started the problem the way I am instructed to start and it produces a grayscale image.Problem 5Use the MATLAB imshow function to load and display the image A stored in the im
