In your desktop MATLAB, build a function named checkerboard(N) which would accept an integer N as input argument and return an N by N square matrix with a checkerboard pattern of 1 and 0 for example, input N=4 should return matrix: 1010 0101 1010 0101 Hints: It seems, what determines whether the element at (i.)) is 1 or 0 is actually whether itj is even or odd? Check if this is true. Check out by HELP or GOOGLE how the built-in function mod(integerA, integerB) works, and how this guy can help determine if an integer is even or odd Your function should be saved in your MATLAB current folder, and can be readily called from the command line same way as a built-in function. For those of you who forget how a function works exactly, go back and check the lecture where the concept was initially introduced Put comments at as many places as you can, as if you are showing other fellow programmers how your function works, as if you are selling your function as a product to customers for easy use with instructions
