Write a MATLAB program that determines if a square matrix, a is symmetric 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. 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: a rectangular matrix, mat2. The program outputs are: 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 -11 0 -12]
