Please solve using MATLAB, thanks!

Programming: 1. Write a function that takes as input dimension n; n x n orthogonal matrix Q; n x n upper triangular matrix n x 1 vector b R; - and outputs the solution to Ax - b using the QR factorization A-QR. Do not use Matlab's built-in transpose operator. a) Write out or print out your function and turn it in. b) Run vour function for the case: 1 [-2 -5 13 Write out or print out your result.
