(in MATLAB language)

Write a script that creates a 5-by-4 array of uniformly distributed (between 0 and 1) random numbers (using rand), then uses a for loop to move through the array, element by element. (Hint: use two nested for loops), setting any value that is less than 0.2 to 0 and any value that is greater than (or equal to) 0.2 to 1.
