How can I write a function called checkerboard

How can I write a function called checkerboard that takes as input two positive integer scalars, n and m, in that order. The function must create and return board, which is an n-­‐by-­‐m matrix. Every element of board is either 0 or 1. The first element, board(1,1) is 1. No direct neighbors in the matrix, vertically or horizontally, can be equal. That is, a 1 element cannot have 1 immediately preceding or following it in the same row or column.

This sounds like a homework question. So please show us, what you have tried so far and ask a specific question.

Hello,

This is what I have,

function board = checkerboard(n , m)
    board = zeros(n,m); 
    board (1:2:n , 1:2:m)=1; 
    board (2:2:n , 2:2:m)=1; 
end

Congratulations - you did it yourself. Do you have any questions?

So what is the problem?

I figured it out on my own but I was really stuck initially. I was looking for help with a starting point. In the I reread the question multiple times then a light went off and my function seemed to work.
