DESCRIPTION

13       NPNTS       (Integer, Input) - The number of input data points.
14
15       X           (Real, Input) - An array containing the  X  coordinates  of
16                   the input data points.
17
18       Y           (Real,  Input)  -  An array containing the Y coordinates of
19                   the input data points.
20
21       Z           (Real, Input) - An array containing the  Z  coordinates  of
22                   the input data points.
23
24       U           (Real,  Input)  - An array containing the functional values
25                   of the input data points.  That is, U(L) is  the  value  of
26                   the  input  function  at  coordinate  (X(L),Y(L),Z(L)), for
27                   L=1,NPNTS.
28
29       NUMXOUT     (Integer, Input) - The number of X  values  in  the  output
30                   grid.
31
32       NUMYOUT     (Integer,  Input)  -  The  number of Y values in the output
33                   grid.
34
35       NUMZOUT     (Integer, Input) - The number of Z  values  in  the  output
36                   grid.
37
38       XO          (Real,  Input)  -  An array of dimension NUMXOUT containing
39                   the X coordinates of the output data grid. The values in XO
40                   must be increasing, but need not be equally spaced.
41
42       YO          (Real,  Input)  -  An array of dimension NUMYOUT containing
43                   the Y coordinates of the output data grid. The values in YO
44                   must be increasing, but need not be equally spaced.
45
46       ZO          (Real,  Input)  -  An array of dimension NUMZOUT containing
47                   the Z coordinates of the output data grid. The values in ZO
48                   must be increasing, but need not be equally spaced.
49
50       UO          (Real,  Output)  - A three-dimensional array dimensioned as
51                   UO(NUMXOUT,NUMYOUT,NUMZOUT)  containing  the   interpolated
52                   functional  values.  UO(I,J,K) is the interpolated value at
53                   grid point (XO(I),YO(J),ZO(K)).
54
55       IER         (Integer, Output) -  An  error  return  value.  If  IER  is
56                   returned as 0, then no errors were detected. If IER is non-
57                   zero, then refer to the  man  page  for  dsgrid_errors  for
58                   details.

USAGE

61       DSGRID3S  is the single precision gridding function in the Dsgrid pack‐
62       age.  The behavior of DSGRID3S is controlled by values set for the var‐
63       ious  parameters  described in dsgrid_params.  Values for these parame‐
64       ters can be set using the subroutines DSSETI, DSSETR, and DSSETC.
65

ACCESS

67       To use DSGRID3S, load the NCAR Graphics library ngmath.
