Method Detail

### interpolate

    MultivariateRealFunction interpolate(double[][] xval,
                                         double[] yval)
                                         throws MathException,
                                                IllegalArgumentException

  Computes an interpolating function for the data set.

  Parameters:
    `xval` - the arguments for the interpolation points. `xval[i][0]` is the first component of interpolation point `i`, `xval[i][1]` is the second component, and so on until `xval[i][d-1]`, the last component of that interpolation point (where `d` is thus the dimension of the space).
    `yval` - the values for the interpolation points
  Returns:
    a function which interpolates the data set
  Throws:
    `MathException` - if arguments violate assumptions made by the interpolation algorithm or some dimension mismatch occurs
    `IllegalArgumentException` - if there are no data (xval null or zero length)
