Question

Given a matrix M (any matrix entries any size): Given matrix M, whit an even number of columns and any number of rows: write a function [A]: c (M) to: Make zero the 1^st half of the columns of matrix M. The rest of the entries in the matrix should be squared. The matrix is called A. The matrix M should be use non-vectorized code Use for much shorter code

Answer 1

m= magic(4)
disp(m)
s1 = m(1:half);
s2 = m(half + 1 : end);
x=zeros(s1);
C = s2.^2;
A=[x,c];
disp(A)
