Modifier and Type	Method	Description
`TrivariateFunction`	`interpolate(double[] xval, double[] yval, double[] zval, double[][][] fval)`	Compute an interpolating function for the dataset.

Method Details
- 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
