Please answer with details.

appreciate your help.

The Hilbert matrices H arise in finding polynomial approximations to functions defined on the unit interval. For example, when approximating the function sin(pix) on [0,1] , the coefficients of the polynomial p(x) of degree n-1 that minimizes the squared error are solutions of the matrix equation Using the following techniques explore the believer of the solutions to (1) for values of n up to 25: using basic Gaussian elimination using Gaussian elimination with (partially) scaled partial pivoting using LU factorization using Gauss - Seidel iteration in each case compute the residual error vector r = b - compare vour results for the three methods.
