Solve the following problem with Matlab using vectors, matrices, and the backslash operator. One of the main challenges of this lab is figuring out how to enter the elements of the matrix quickly and reliably. For a small matrix, it's easy to type out the matrix explicitly like
A = [ 1 9 7 ; 4 3 8 ; 6 2 0], but for a 13 x 13 matrix with 169 elements, that's tedious and error prone.
