c_dspnt3s - interpolate single precision 3D data at specified
points
void c_dspnt3s(int, float [], float [], float [], float[]
int, float [], float [], float [], float *, int *);
void c_dspnt3d(int n, float xi[], float yi[], float zi[], float ui[],
int m, float xo[], float yo[], float zo[], float *uo,
int *ier)
- n
- The number of input data points.
- xi
- An array containing the X coordinates of the input data points.
- yi
- An array containing the Y coordinates of the input data points.
- zi
- An array containing the Z coordinates of the input data points.
- ui
- An array containing the functional values of the input data points. That
is, ui[l] is the value of the input function at coordinate
(xi[l],yi[l],zi[l]), for 0 <= l < n .
- m
- The number of output data points (this may be "1").
- xo
- An array of dimension m containing the X coordinates of the output data.
The values in xo may be in any order.
- yo
- An array of dimension m containing the Y coordinates of the output data.
The values in xo may be in any order.
- zo
- An array of dimension m containing the Z coordinates of the output data.
The values in xo may be in any order.
- uo
- A pointer to a float. Space for m floats is allocated for uo by dspnt3d.
zo[i] is the interpolated value at point (xo[i],yo[i],zo[i]) for 0 <= i
< n .
- ier
- 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.
This function is called to interpolate single precision 3D data at
a specified point or points.
To use c_dspnt3s, load the NCAR Graphics library ngmath.
dsgrid, dsgrid_params.
