Explanation / Answer

Ans)

Matlab Code

-----------------

function a = checkerboard(n)
%CHECKERBOARD Summary of this function goes here
% Detailed explanation goes here

% case of even rows
if mod(n, 2) == 0
a = ones(n + 1, n); % create a matrix of ones having a plus row
a(2 : 2 : end) = 0; % select every second element
a(end, :) = []; % remove the last row from the matrix
else
a = ones(n, n); % create the matrix of ones
a(2 : 2 : end) = 0; % select every second element
end

end

-----------------------------------

Run in command window as below

>> checkerboard(5)

ans =

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
