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.m. For example, if we want to use a cubic (degree 3) polynomial and 6 data points, then 1sdata.m should contain 7 5 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 and the data points. You may not use the Matlab command polyfit. Also, what is the relationship between n and m that must exist for the least squares problem to make sense? If the relationship does not hold, deal with this appropriately
