*DECK DDNTP SUBROUTINE DDNTP (H, K, N, NQ, T, TOUT, YH, Y) C***BEGIN PROLOGUE DDNTP C***SUBSIDIARY C***PURPOSE Subroutine DDNTP interpolates the K-th derivative of Y at C TOUT, using the data in the YH array. If K has a value C greater than NQ, the NQ-th derivative is calculated. C***LIBRARY SLATEC (SDRIVE) C***TYPE DOUBLE PRECISION (SDNTP-S, DDNTP-D, CDNTP-C) C***AUTHOR Kahaner, D.
