I'm supposed to write a function with header [M] = myCheckerBoard(n) and M is an n by n matrix, how do I do this?

M = [1 0 1 0 1; 0 1 0 1 0; 1 0 1 0 1; 0 1 0 1 0;1 0 1 0 1]

I had a function written but it didn't work. I did the first step with zeros, but I'm not sure on where to proceed from there

You could write two nested for-loops over the elements of M and fill in the 1's inside those loops.

Hi, I understand you are trying to make a checkerboard function. You can do this by two nested for loops. Here is a sample code for it.

function M = myCheckerBoard(n)
   M = zeros(n,n);
   for j = 1:n
       if mod(j,2)==1 
           for i =1:2:n
               M(j,i) = 1;
           end
       elseif mod(j,2)==0 
           for t = 2:2:n
               M(j,t) = 1;
           end
       end
   end
end
