Using MATLAB 3. Write a script to ask the user three student names and print the known grades against each name as well as the average.

4. Write a script to prompt the user for a random matrix (3x4) which it's elements range is between -5 and 5 then print the elements that are greater than 2

3- Write a script to ask the user three student names and print the known grades against each name as well as the average of them. Grades of student 1: Grades of student 2: Grades of student 3: 35 55 42 78 Your printed result should be like this: Alex Sue Petter 90.00 88.00 35.00 80.00 56.00 55.00 75.00 100.00 42.00 62.00 73.00 78.00 mean 76.75 79.25 52.50 4- Write a script to prompt the user for a random matrix (3x 4) which its elements range is between -5 and 5 then print the elements that are greater than 2
