NAME¶
NNPNTINITS- Enter single point mode
SYNOPSIS¶
CALL NNPNTINITS (NPNTS, X, Y, Z)
DESCRIPTION¶
- NPNTS
- (Integer, Input) - The number of input data points. (NPNTS > 3).
- X
- (Real, Input) - An array of dimension NPNTS containing the X coordinates
of the input data points.
- Y
- (Real, Input) - An array of dimension NPNTS containing the Y coordinates
of the input data points.
- Z
- (Real, Input) - An array of dimension NPNTS containing the functional
values of the input data points. That is, Z(L) is the value of the input
function at coordinate (X(L),Y(L)), for L=1,NPNTS.
USAGE¶
This subroutine is called when you want to interpolate at individal points. It
is an initialization routine that sets up some internal variables and does
this initial triangulation. To actually do the interplation, use subroutine
NNPNTS. To terminate single point mode, use the subroutine NNPNTEND.
ACCESS¶
To use NNPNTINITS, load the NCAR Graphics library ngmath.
