| See also: | Bsplineevalgd Fourierevalgd |
| Quantlet: | polyevalgd | |
| Description: | computes polynomial basis and its derivatives. |
| Usage: | polyevalgd (argvals, nbasis {,deriv, omega}) | |
| Input: | ||
| argvals | n x m matrix, arguments | |
| nbasis | scalar, number of basis functions | |
| deriv | r x 1 vector of integers (>= 0), optional, contains the orders of derivatives to compute. If deriv = 0 the actual Fourier bases will be calculated. The default value is deriv = 0. | |
| omega | scalar, optional, shift parameter (default = 0) | |
| Output: | ||
| phi | (n x nbasis x rows(deriv) x m) array, values of the basis functions (and its derivatives) | |
