That is, U(L) is the value of the input function at coordinate (X(L),Y(L),Z(L)), for L=1,NPNTS. .IP NUMXOUT 12 (Integer, Input) - The number of X values in the output grid. .IP NUMYOUT 12 (Integer, Input) - The number of Y values in the output grid. .IP NUMZOUT 12 (Integer, Input) - The number of Z values in the output grid. .IP XO 12 (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. .IP YO 12 (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. .IP ZO 12 (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. .IP UO 12 (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)). .IP IER 12 (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. .SH 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. .SH ACCESS To use DSGRID3S, load the NCAR Graphics library ngmath. .SH SEE ALSO dsgrid, dsgrid_params, dsseti, dsgeti, dssetr, dsgetr, dssetc, dsgetc. .sp Complete documentation for Dsgrid is available at URL .sp http://ngwww.ucar.edu/ngdoc/ng/ngmath/dsgrid/dshome.html .SH COPYRIGHT Copyright (C) 2000 .br University Corporation for Atmospheric Research .br The use of this Software is governed by a License Agreement.
