Computer Question 1: Subplot Write Matlab code that does the following: 1) Begins by setting A = [ 1:10 ; 31:40 ; 26:2:44 ]; 2) Then, your program should calculate the sum of each row of A . If, and only if, the sum of any of the rows of the matrix A is at least 350, your program should display the following two graphs next to each other using subplot, with x containing 243 points running from 1 to 20.: y = x 3 + 2x y = x 4 - 10000 sin(x) Your graph should look like this: Computer Question 2: Product of Composites Run the following commands, which create a 100 element matrix B : rand( 'state' , 4 ) ; B = round( 120*rand(10,10) - 10 ); Write Matlab code that calculates the product of all of the numbers in B after eliminating the following numbers: a) Those that are prime numbers b) Those that are less than 0 or greater than 100 Display the following statement using fprintf, substituting in the values you find: "The product of all composite numbers in B between 0 and 100, inclusive, is ___" You cannot use loops in any part of your answer this question; you must use
