1) Write Matlab code to implement the discrete least squares method of finding the best-fit polynomial of degree n for a set of m data points The pertinent information should be read from a data file called lsdata.im For example, if we want to use a cubic (degree 3) polynomial and 6 data points, then 1sdata.m should contain where the first two entries are respectively n and m and the remaining rows contain the coordinates of the 6 data points Your program should produce a picture of the least squares polynomial an
