**NAME**

c_dspnt3s - interpolate single precision 3D data at specified points

**FUNCTION** **PROTOTYPE**

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

**SYNOPSIS**

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)

**DESCRIPTION**

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.

**USAGE**

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

**ACCESS**

To use c_dspnt3s, load the NCAR Graphics library ngmath.
