Write a function with one input integer argument that returns an output matrix(MQ) which is a 2n by 2n matrix. MQ consist of 4 n-by-n submatrices top left are all ones top right corner are all 2's bottom left are 3's and bottom right are 4's

function [MQ] = myquadrants(n) I don't know how to set up the matrix

Answer 1

[Massimo Zanetti]

Here it is.

function MQ = myquadrants(n)
  MQ=[ones(n),2*ones(n);
      3*ones(n),4*ones(n)];
end
