CALL DSPNT2D (N, X, Y, Z, M, XO, YO, ZO, IER)

N

(Integer, Input) - The number of input data points.

X

(Double precision, Input) - An array containing the X coordinates of the  input data points.

Y

(Double precision, Input) - An array containing the Y coordinates of the  input data points.

Z

(Double precision, Input) - An array containing the functional values of the  input data points. That is, Z(L) is the value of the input function at coordinate (X(L),Y(L)), for L=1,N.

M

(Integer, Input) - The number of output data points (this may be "1").

XO

(Double precision, Input) - An array of dimension M containing  the X coordinates of the output data. The values in XO may be in any order.

YO

(Double precision, Input) - An array of dimension M containing  the Y coordinates of the output data. The values in YO may be in any order.

ZO

(Double precision, Output) - An array of dimension M containing  the interpolated values. ZO(I) is the interpolated value at  point (XO(I),YO(I)) for I=1,M.

IER

(Integer, Output) - 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 for details.

This subroutine is called when you want to interpolate at an individual point or points.

To use DSPNT2D, load the NCAR Graphics library ngmath.

dsgrid, dsgrid_params.
