I see in the MKL 2017 release note that the Hyman monotonic cubic spline is available, but I didn't manage to find how to use it in the MKL developer reference guide. Can you help me or provide me an example please ?
Thanks a lot.
The help seams to not have been updated or lost. I did see it once in the help for XE2019 but its gone now. I tried it biefly and it worked.
The include file mkl_df.f90 includes these defintions for spline type:
INTEGER(KIND=4) DF_PP_DEFAULT INTEGER(KIND=4) DF_PP_SUBBOTIN INTEGER(KIND=4) DF_PP_NATURAL INTEGER(KIND=4) DF_PP_HERMITE INTEGER(KIND=4) DF_PP_BESSEL INTEGER(KIND=4) DF_PP_AKIMA INTEGER(KIND=4) DF_LOOKUP_INTERPOLANT INTEGER(KIND=4) DF_CR_STEPWISE_CONST_INTERPOLANT INTEGER(KIND=4) DF_CL_STEPWISE_CONST_INTERPOLANT INTEGER(KIND=4) DF_PP_HYMAN PARAMETER (DF_PP_DEFAULT = 0) PARAMETER (DF_PP_SUBBOTIN = 1) PARAMETER (DF_PP_NATURAL = 2) PARAMETER (DF_PP_HERMITE = 3) PARAMETER (DF_PP_BESSEL = 4) PARAMETER (DF_PP_AKIMA = 5) PARAMETER (DF_LOOKUP_INTERPOLANT = 6) PARAMETER (DF_CR_STEPWISE_CONST_INTERPOLANT = 7) PARAMETER (DF_CL_STEPWISE_CONST_INTERPOLANT = 8) PARAMETER (DF_PP_HYMAN = 9)
Note the last parameter defines the Hyman type.
Specify constant DF_PP_HYMAN when calling dfdeditppspline1d
