Given A is a square matrix, find the sum of the anti-diagonal of A The anti-diagonal of a matrix is the one that leads from the top-right to the bottom-left For example, if the given matrix is A = [13 23 0 3 17 13 7 0 0 -11 19 23 5 0 17 19] then the sum of the anti-diagonal elements is =A(1, 4)+A(2, 3)+A(3, 2)+A(4, l)=3+7+(-11)+5=4 a) Find the sum of the anti-diagonal elements of B b) The input is a square matrix B. The input matrix is given to be square but can be any size. c) You have to use loop(s) or/and conditional statement(s) to do the problem. You cannot use the MATLAB sum or equivalent commands. d) Test the program for input of B = [1 2 0 4 -5 33 81 1 5 04 0 8 77 1 30 80]
