man c_dspnt3s (3): interpolate single precision 3D data at specified points

FUNCTION PROTOTYPE

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.
