ncl_nnpntd: Interpolate at a single point in double precision

NAME

NNPNTD- Interpolate at a single point in double precision

SYNOPSIS

CALL NNPNTD (X, Y, Z)

DESCRIPTION

X
(Double precision, Input) - The X coordinate of the point where interpolation is desired.
Y
(Double precision, Input) - The Y coordinate of the point where interpolation is desired.
Z
(Double precision, Output) - The interpolated functional value at the point (X,Y).

USAGE

This subroutine is called when you want to interpolate at an individal point. NNPNTINITD must be called prior to calling NNPNTD and NNPNTENDD must be called to terminate single point mode.

ACCESS

To use NNPNTD, load the NCAR Graphics library ngmath.
