P#3. Toepliz MatriX. The Buffalo Fan

A two-dimensional array is input and your code finds whether the given input matrix is Toepliz or not. In linear algebra, a Toeplitz matrix or diagonal-constant matrix, named after Otto Toeplitz (German mathematician), is a matrix in which each descending diagonal from left to right is constant. E.g.,

A and B are Toeplitz but C is not. Test your code with these 3 matrixes (one at a time, of course). Should size each array, e.g., [m.n]=size(array).

(I need this in Matlab, Thank you!)
