1,3, and 4 please! thank you

EXERCISES Chapter 28 What Are Special Types of Matrices? 1. Write a MATLAB program that determines if a square matrix, A is s ymmetric or not. Use your knowledge of loops and/or conditional statements to write the program. The program needs to work for a square matrix of any size. 2. ogram. The progam nees t 3. Without using the max, min or similar MATLAB commands, write a program that outputs the maximum and minimum element values of any rectangular matrix. The program input is: 1) a rectangular matrix, mat2. The program outputs are: 1) 2) the maximum value, big, and the minimum value, small. Test and run your program for the following matrix, mat2. -1 0 2 7 -4 12 4 8.2 11 4. Write a program in MATLAB that for a square matrix subtracts the sum of the ct of the or any other absolute value of the elements above the diagonal from the produ absolute value of the diagonal elements. You cannot use the sum similar MATLAB commands to solve this problem. Use your knowledge o and/or conditional statements to write the program. The program input is: 1) a square matrix, matl. The program output is: 1) the value of the difference, re_mat. Test and run your program for the following 4x 4 matrix, matl. EXERCISES Chapter 28 What Are Special Types of Matrices? 1.
