DSGRID3D - double precision Fortran entry for 3D gridding
CALL DSGRID3D (NPNTS, X, Y, Z, U, NUMXOUT, NUMYOUT, NUMZOUT,
XO, YO, ZO, UO, IER)
- NPNTS
- (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,NPNTS.
- NUMXOUT
- (Integer, Input) - The number of X values in the output grid.
- NUMYOUT
- (Integer, Input) - The number of Y values in the output grid.
- NUMZOUT
- (Integer, Input) - The number of Z values in the output grid.
- XO
- (Double precision, Input) - An array of dimension NUMXOUT containing the X
coordinates of the output data grid. The values in XO must be increasing,
but need not be equally spaced.
- YO
- (Double precision, Input) - An array of dimension NUMYOUT containing the Y
coordinates of the output data grid. The values in YO must be increasing,
but need not be equally spaced.
- ZO
- (Double precision, Input) - An array of dimension NUMZOUT containing the Z
coordinates of the output data grid. The values in ZO must be increasing,
but need not be equally spaced.
- UO
- (Double precision, Output) - A three-dimensional array dimensioned as
UO(NUMXOUT,NUMYOUT,NUMZOUT) containing the interpolated functional values.
UO(I,J,K) is the interpolated value at grid point
(XO(I),YO(J),ZO(K)).
- 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.
DSGRID3D is the single precision gridding function in the Dsgrid
package. The behavior of DSGRID3D is controlled by values set for the
various parameters described in dsgrid_params. Values for these parameters
can be set using the subroutines DSSETI, DSSETRD, and DSSETC.
To use DSGRID3D, load the NCAR Graphics library ngmath.
dsgrid, dsgrid_params, dsseti, dsgeti, dssetrd dsgetrd dssetc,
dsgetc.
