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.
