ncl_natgrid (3) Linux Manual Page
Natgrid is a package for gridding 2D randomly-spaced data using
a natural neighbor algorithm. Single precison and double
precision interfaces exist in both Fortran and C.Synopsis
FORTRAN single precision
———————— c_natgridd – primary function for gridding.
c_nnseti – set int parameter values.
c_nngeti – retrieve values for int parameters.
c_nnsetrd – set double parameter values.
c_nngetrd – retrieve values for double parameters.
c_nnsetc – set char valued parameters.
c_nngetc – retrieve values for char parameters.
c_nngetsloped – get slope values, if calculated.
c_nngetaspectd – get aspect values, if calculated.
c_nnpntinitd – initiate single point mode.
c_nnpntd – interpolate at a single point.
c_nnpntendd – terminate single point mode. Fortran double precision (not supported on UNICOS):
