using matlab with screen shot

Write a Matlab program to sample a message signal x=5cos(2fmt), (where fm= 50Hz is the signal frequency) using a flat top sampling type where the frequency of the carrier signal fc=200Hz with a unity amplitude square wave then quantizes it where the number of bits n=5. Plot the message signal (red color), the carrier signal (blue color) , the quantized signal (green color), and quantization error
