NAME

       c_nnpntinits - Enter single point mode

FUNCTION PROTOTYPE

       void c_nnpntinits(int, float [], float [], float []);

SYNOPSIS

       void c_nnpntinits (npnts, x, y, z);

DESCRIPTION

       npnts       The number of input data points. (npnts > 2)

       x           An array of size npnts containing the X coordinates of the input data points.

       y           An array of size npnts containing the Y coordinates of the input data points.

       z           An array of size npnts containing the functional values of the input data
                   points. That is, z[n] is the value of the input function at coordinate
                   (x[n],y[n]), for 0 <= n < npnts.

USAGE

       This function is invoked when you want to interpolate at individal points.  It is an
       initialization routine that sets up some internal variables and does this initial
       triangulation. To actually do the interplation, use function c_nnpnts.  To terminate
       single point mode, use the function c_nnpntend.

ACCESS

       To use c_nnpntinits, load the NCAR Graphics library ngmath.
