NAME¶
DSPNT2S - Interpolate at a single point (or points) in 2D in single precision
SYNOPSIS¶
CALL DSPNT2S (N, X, Y, Z, M, XO, YO, ZO, IER)
DESCRIPTION¶
- N
- (Integer, Input) - The number of input data points.
- X
- (Real, Input) - An array containing the X coordinates of the input data
points.
- Y
- (Real, Input) - An array containing the Y coordinates of the input data
points.
- Z
- (Real, Input) - An array 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,N.
- M
- (Integer, Input) - The number of output data points (this may be
"1").
- XO
- (Real, Input) - An array of dimension M containing the X coordinates of
the output data. The values in XO may be in any order.
- YO
- (Real, Input) - An array of dimension M containing the Y coordinates of
the output data. The values in YO may be in any order.
- ZO
- (Real, Output) - An array of dimension M containing the interpolated
values. ZO(I) is the interpolated value at point (XO(I),YO(I)) for
I=1,M.
- IER
- (Integer, Output) - An error return value. If IER is returned as 0, then
no errors were detected. If IER is non-zero, then refer to the man page
for dsgrid_errors for details.
USAGE¶
This subroutine is called when you want to interpolate at an individual point or
points.
ACCESS¶
To use DSPNT2S, load the NCAR Graphics library ngmath.
