ncl_dsgrid3s: single precision Fortran entry for 3D gridding

NAME

DSGRID3S - single precision Fortran entry for 3D gridding

SYNOPSIS

CALL DSGRID3S (NPNTS, X, Y, Z, U, NUMXOUT, NUMYOUT, NUMZOUT, XO, YO, ZO, UO, IER)

DESCRIPTION

NPNTS

(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 Z coordinates of the input data points.

U

(Real, 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

(Real, 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

(Real, 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

(Real, 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

(Real, 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.

USAGE

DSGRID3S is the single precision gridding function in the Dsgrid package. The behavior of DSGRID3S is controlled by values set for the various parameters described in dsgrid_params. Values for these parameters can be set using the subroutines DSSETI, DSSETR, and DSSETC.

ACCESS

To use DSGRID3S, load the NCAR Graphics library ngmath.
