## Homework Statement

The link http://www.york.ac.uk/depts/maths/data/ts/welcome.htm gives the average monthly temperature T in Fahrenheits for Dubuque, Iowa from 1964 to 1975. Let T = a

_{0}+ sum from i = 1 to k of a

_{i}cos(2*pi*i*m/12) + sum from i = 1 to k of b

_{i}sin(2*pi*i*m/12) where m is the number of months from January, 1964.

Use the SVD and matlab to find suitable values of a and b for k = 2 and k = 4. As part of your answer include a plot which displays the data abd T for k = 2 and k = 4.
