Use MATLAB built in functions to analyze the data of grades for 5 students and 3 homework assignments

(a) Create a matrix named grades that contains the data

(b) Calculate the number of elements of the matrix.

(c) Calculate the size of the matrix (should have vector with 2 elements)

(d) Round the grades for HW 2 to the neartest integer - save it in your original grades matrix.

HW1 HW2 HW3 Student 1 100 98.5 85 Student 2 95 75.1 80 Student 3 90 85.7 85 Student 4 100 100. 3 95 Student5 80 85.6 85 2 2
