DSPNT3D - Interpolate at a single point (or points) in 3D in
double precision
CALL DSPNT3D (N, X, Y, Z, U, M, XO, YO, ZO, UO, IER)
- N
- (Integer, Input) - The number of input data points.
- X
- (Double precision, Input) - An array containing the X coordinates of the
input data points.
- Y
- (Double precision, Input) - An array containing the Y coordinates of the
input data points.
- Z
- (Double precision, Input) - An array containing the Z coordinates of the
input data points.
- U
- (Double precision, Input) - An array containing the functional values of
the input data points. That is, U(L) is the value of the input function at
coordinate (X(L),Y(L),Z(L)), for L=1,N.
- M
- (Integer, Input) - The number of output data points (this may be
"1").
- XO
- (Double precision, Input) - An array of dimension M containing the X
coordinates of the output data. The values in XO may be in any order.
- YO
- (Double precision, Input) - An array of dimension M containing the Y
coordinates of the output data. The values in YO may be in any order.
- ZO
- (Double precision, Input) - An array of dimension M containing the Z
coordinates of the output data. The values in ZO may be in any order.
- UO
- (Double precision, output) - An array of dimension M containing the
interpolated values. UO(I) is the interpolated value at point
(XO(I),YO(I),ZO(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.
This subroutine is called when you want to interpolate at an
individual point or points.
To use DSPNT3D, load the NCAR Graphics library ngmath.
dsgrid, dsgrid_params.
