Chapter 18: Matrix Manipulation 161toeplitz (c, r)Function FileReturn the Toeplitz matrix constructed given the first column c, and (optionally) thefirst row r. If the first element of c is not the same as the first element of r, the firstelement of c is used. If the second argument is omitted, the first row is taken to bethe same as the first column.A square Toeplitz matrix has the form:⎡c 0 r 1 r 2 · · · r n⎤c n c n−1 c n−2 . . . c 0 c 1 c 0 r 1 · · · r n−1c 2 c 1 c 0 · · · r n−2⎢⎣. ⎥. . . .. . ⎦vander (c)Return the Vandermonde matrix whose next to last column is c.A Vandermonde matrix has the form:⎡c n−11 · · · c 2 ⎤1 c 1 1c n−12 · · · c 2 2 c 2 1⎢⎣ .. ..⎥. . . ⎦c n−1n · · · c 2 n c n 1Function File
