MATLAB: How to separate odd and even elements of a matrix with out using for or while loops.

Question

a function that takes a matrix A of positive integers as an input and returns two row vectors. The first one contains all the even elements of A and nothing else, while the second contains all the odd elements of A and nothing else, both arranged according to column-­‐major order of A. without using for loops or while loops.

i am using this approach, where r vector contains the row position of odd elemets and c vector contains the coloumn position of odd elements

function [o e] = separate_by_two(A)
B = mod(A,2)
[r c] = find(B);

now dont know how to make a vector conatining all the odd and even elements.

Answer 1

t_odd = rem(A,2) ~= 0;
namber_odd = A(t_odd);
namber_even = A(~t_odd);
