Task II: Fun with Nested Loops [85 points] In a script file named LASTNAM E L TASK2. m, write a program according to the specifications AB9_T outlined below Before starting, clear all variables in the MATLAB Workspace and the contents of the MATLAB Command Window. Unless specified, suppress all MATLAB Command Window output. After completing the program, your program output should look similar to the output shown below ASTNAM ELL AB9-T nter the number of rows for tri r the number of columns for the matrix Ente 50 -42 33 -46 41 17 28 20 26 41. 21 10 13 25 20 -41 39 23 of row B1 is -52 Tota of row E2 is Tota 28 of row E3 is 17 Tota of row E4 is -4 ota of row is ota 166 of all elements Tota 263 Mean of all elements S -8.767 of column 1 i s -41 and is in row 2 of column 2 s -44 and is of column s -46 and is of column 4 i s -42 and is of column s -49 and is of column 6 46 and is of a 11 the elemen ts is -49 n row 5 and column 5 (a) [2 points] Create a variable named num rows and assign to it a scalar obtained from prompting the ser with the prompt string 'Enter the number of rows for a matrix You may ass Ume the user will enter a positive integer scalar (b) [2 points Create a variable named num columns and assign to it a scalar obtained from prompting r with the prompt string Enter the number of columns for the matrix You the use may assume the user will enter a positive integer scalar (c) [4 points] Create a variable named mat and assign to it a num rows x num columns matrix of random integers chosen uniformly from the closed interval C-50, 50] (d) 12 points] Display mat using built-in function dispO (e) [25 points] Do the following with n ested for-end statements.
