8. (10 pts) (a) The Hilbert matrix Hn is an nxn matrix in which entry ij is 1/(itj-1). Use your pipedO program to draw H3, and H3-1. Note that H3 can be obtained by a function call to find a matrix inverse in the software used. (b) The Vandermonde matrix V3(u,v,w) is a 3x3 matrix in which row one is [l,u,u-], row 2 is [1,v,v-], and row draw V3(1, 1.5, 2), and V3(1, 2, 3), as well as their inverses and transposes. 3 is [I, w.w?]. Use your piped program to
