How to write a Function that returns a matrix

Write a function named checkerBoard that will receive a positive integer n as an input argument. The function will return an n-by-n matrix made up of alternating ones and zeros as shown in the example below. The first element of the matrix returned (first row, first column: ans(1,1) ) should be 1. I'm stuck on how to write the for loop?

There is no "example below". It sounds like you've copied the text of your homework assignment without showing any own effort to solve the problem. Please post, what you have tried so far.

Sarah, this is obviously homework. So what have you tried so far? Any ideas of how to generate the checkerboard?

[Sarah Sadeq]

I tried this right her

function [ mat ] = checkboard(n)
mat=zeros(n,n);
if rem(n+1,2)==0
mat(1:2:end,2)=1;
mat(2:2:end,2)=1;
else 
    mod(n,n);
    mat(1:2:end)=1;
 end
end

However, it doesn't work

[Walter Roberson]

mod(n,n); doesn't do anything useful. It calculates a value and then throws the value away.

Maybe try checkerboard(1,2,2)==0?

[Sarah Sadeq]

should I use the if statement?
