Write a Matlab function to implement reduced QR decomposition in Matlab. Your solution should be in a file named qr_decomp.m whose first line is function [Q, R] = qr-decomp(A) You can use the pseudocode on page 90 of the course notes as a guide. You can assume that A is a matrix with full rank (i.e., with linearly independent columns) but you should not asume that it is square. You should test your code enough that you are reasonably confident it is correct. You have several examples between class, the last homework and the course notes, and you can also test your code on new matrices and check that QR = A and that and R have the requisite properties
