This requires 2 .m files, one for the function, and another to call the function. (All to be done on matlab)

Homework 7: Due when you enter lecture next week. 1. Write a function (called rsquared.m) that computes the correlation coefficient for a linear fit. You should only need 4 inputs: Xi, Yi, A, and B. Try your function out on the following: the pressure and temperature of steam are related by b/T Given the following data, use MATLAB find the appropriate values of a and b. Write and use a MATLAB function to compute r2 for the fit.
