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, use the backslash operator where appropriate for all remaining problems as well.
