I'm getting errors while typing the code. Confused on how I can call on a frprintf() command with a vector.

Problem 2. Write a function called my_size that takes a two-dimensional ar- ray (matrix) as an input argument (you do not have to check the input argu- ment) and returns the size of the matrix just as the built-in size function would do. However, my_size also prints out the dimensions of the matrix as illustrated by this run: >> s = my_size (randi (10,20,30)) This is a 20-by-30 matrix 20 30
