Solve the question using MATLAB please, I need the code!

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, 1) = 3 + 7 + (-11) + 5 = 4 Specifications Find the sum of the anti-diagonal elements of B. The input is a square matrix B. The input matrix is given to be square but can be any size. You have to use loop(s) or/and conditional statement(s) to do the problem. You cannot use the MATLAB sum or equivalent commands. Test the program for input of B = [1 2 0 4 -5 33 81 1 5 14 0 8 77 1 30 80]
