Hello dear friends, I ask you for help with this exercise:

Develop a function called imp_index that takes an array M as input argument and returns an array containing the elements of M that are in the odd columns and rows.

Thanks for your help

So far I have developed this code:

function out = imp_index(M)
M=A(1:2:end,1:2:end);
M=A(1:2:end,2:2:end);
M=A(2:2:end,1:2:end);
M=A(2:2:end,2:2:end);
end
