MATLAB

Write a function that takes one input, an integer number n, and returns a matrix that is n times n, where the value of each number is the distance from the upper-left to bottom-right diagonal. Numbers below the diagonal should be negative, and numbers above the diagonal should be positive. For example, if your input was 5, your output would be: 0 -1 -2 -3 -4 1 0 -1 -2 -3 2 1 0 -1 -2 3 2 1 0 -1 4 3 2 1 0
