• interpolate

  TrivariateFunction interpolate(double[] xval,
                               double[] yval,
                               double[] zval,
                               double[][][] fval)
                                 throws NoDataException,
                                        NumberIsTooSmallException,
                                        DimensionMismatchException,
                                        NonMonotonicSequenceException

  Compute an interpolating function for the dataset.

  Parameters:

  xval - All the x-coordinates of the interpolation points, sorted in increasing order.

  yval - All the y-coordinates of the interpolation points, sorted in increasing order.

  zval - All the z-coordinates of the interpolation points, sorted in increasing order.

  fval - the values of the interpolation points on all the grid knots: fval[i][j][k] = f(xval[i], yval[j], zval[k]).

  Returns:

  a function that interpolates the data set.

  Throws:

  NoDataException - if any of the arrays has zero length.

  DimensionMismatchException - if the array lengths are inconsistent.

  NonMonotonicSequenceException - if arrays are not sorted

  NumberIsTooSmallException - if the number of points is too small for the order of the interpolation
