Write a function called "RoundZero()" that iterates through each value in a matrix and rounds positive numbers to the nearest integer, and sets negative numbers equal to zero.

Your function takes a single input variable:

• M - a matrix of floating point double numbers.

Your function has three outputs:

• Mout - the matrix with rounded and zeroed values
• nr - the number of positive elements rounded.
• n0 - the number of negative elements set to zero, or originally zero.
