2) Write down the linear system to be satisfied by the interpolating line ao + aix,-Vi, i = 1, 2, ,n if it were to interpolate all the given data points. In a matrix form (Xa -y) 1 T1 y1 a1 X is called a design matrix, a is the parameter vector, and y is the observation vector. Multiply Xa-y by X from the left to get the normal equation Solve this (normal) system. Aa-b in Matlab using the command: >>a-Ab Solve the system Xa y in Matlab using the command: >>a-ny What did you observe? What is your conclusion? 2) Write down the linear system to be satisfied by the interpolating line ao + aix,-Vi, i = 1, 2, ,n if it were to interpolate all the given data points.
