HOMEWORK ASSIGNMENT 5 EGM 3344 Regression and Interpolation Concepts Problems from Chapra book chapters 13 through 16 For all of these problems, feel free to use a simple Matlab program to calculate function values (like using a calculator) when the indicated approach is by hand. For problems in Chapter 15, you will frequently need to choose the best points to use for fitting a polynomial of specified degree. For example, if you are given 5 points ( x , y ) and asked to fit a cubic polynomial, you should chose the 4 points whose x values are closest to the value at which the interpolated result y is desired. Problem Approach Comments 13.5 Matlab To solve the overdetermined linear system A xb = for the unknown coefficients in the x vector, use 1 () ( ) TT x AA Ab = . 13.7 Matlab To linearize, divide by x and take the natural logarithm. To solve the overdetermined linear system for the unknown coefficients, use the Matlab backslash (\) operator. Unless stated otherwise,
