FUNCTION PROTOTYPE

9       void c_dspnt3s(int, float [], float [], float [], float[]
10       int, float [], float [], float [], float *, int *);

SYNOPSIS

13       void c_dspnt3d(int n, float xi[], float yi[], float zi[], float ui[],
14                      int m, float xo[], float yo[], float zo[], float *uo,
15                      int *ier)
16

DESCRIPTION

18       n           The number of input data points.
19
20       xi          An array containing the X coordinates of the input data
21                   points.
22
23       yi          An array containing the Y coordinates of the input data
24                   points.
25
26       zi          An array containing the Z coordinates of the input data
27                   points.
28
29       ui          An array containing the functional values of the input data
30                   points. That is, ui[l] is the value of the input function
31                   at coordinate (xi[l],yi[l],zi[l]), for 0 <= l < n .
32
33       m           The number of output data points (this may be "1").
34
35       xo          An array of dimension m containing the X coordinates of the
36                   output data. The values in xo may be in any order.
37
38       yo          An array of dimension m containing the Y coordinates of the
39                   output data. The values in xo may be in any order.
40
41       zo          An array of dimension m containing the Z coordinates of the
42                   output data. The values in xo may be in any order.
43
44       uo          A pointer to a float. Space for m floats is allocated for
45                   uo by dspnt3d. zo[i] is the interpolated value at point
46                   (xo[i],yo[i],zo[i]) for 0 <= i < n .
47
48       ier         An error return value. If *ier is returned as 0, then no
49                   errors were detected. If *ier is non-zero, then refer to
50                   the man page for dsgrid_errors.
51

USAGE

53       This function is called to interpolate single precision 3D data at a
54       specified point or points.
