DESCRIPTION

13       N           (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 the
26                   input function at coordinate (X(L),Y(L),Z(L)), for L=1,N.
27
28       M           (Integer,  Input)  - The number of output data points (this
29                   may be "1").
30
31       XO          (Real, Input) - An array of dimension M  containing  the  X
32                   coordinates  of the output data. The values in XO may be in
33                   any order.
34
35       YO          (Real, Input) - An array of dimension M  containing  the  Y
36                   coordinates  of the output data. The values in YO may be in
37                   any order.
38
39       ZO          (Real, Input) - An array of dimension M  containing  the  Z
40                   coordinates  of the output data. The values in ZO may be in
41                   any order.
42
43       UO          (Real, output) - An array of  dimension  M  containing  the
44                   interpolated  values.  UO(I)  is  the interpolated value at
45                   point (XO(I),YO(I),ZO(I)) for I=1,M.
46
47       IER         (Integer, Output) -  An  error  return  value.  If  IER  is
48                   returned as 0, then no errors were detected. If IER is non-
49                   zero, then refer to the  man  page  for  dsgrid_errors  for
50                   details.
51

USAGE

53       This subroutine is called when you want to interpolate at an individual
54       point or points.
