NAME¶
Natgrid - 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------------------------
NATGRIDS - primary function for gridding. NNSETI - set INTEGER parameter values. NNGETI - retrieve values for INTEGER parameters. NNSETR - set REAL parameter values. NNGETR - retrieve values for REAL parameters. NNSETC - set CHARACTER valued parameters. NNGETC - retrieve values for CHARACTER parameters. NNGETSLOPES - get slope values, if calculated. NNGETASPECTS - get aspect values, if calculated. NNPNTINITS - initiate single point mode. NNPNTS - interpolate at a single point. NNPNTEND - terminate single point mode.
Fortran double precision (not supported on UNICOS):
--------------------------------------------------
NATGRIDD - primary function for gridding. NNSETI - set INTEGER parameter values. NNGETI - retrieve values for INTEGER parameters. NNSETRD - set DOUBLE PRECISION parameter values. NNGETRD - retrieve DOUBLE PRECISION parameters. NNSETC - set CHARACTER valued parameters. NNGETC - retrieve values for CHARACTER parameters. NNGETSLOPED - get slope values, if calculated. NNGETASPECTD - get aspect values, if calculated. NNPNTINITD - initiate single point mode. NNPNTD - interpolate at a single point. NNPNTENDD - terminate single point mode.
C single precision:
------------------
c_natgrids - primary function for gridding. c_nnseti - set int parameter values. c_nngeti - retrieve values for int parameters. c_nnsetr - set float parameter values. c_nngetr - retrieve values for float parameters. c_nnsetc - set char valued parameters. c_nngetc - retrieve values for char parameters. c_nngetslopes - get slope values, if calculated. c_nngetaspects - get aspect values, if calculated. c_nnpntinits - initiate single point mode. c_nnpnts - interpolate at a single point. c_nnpntend - terminate single point mode.
