Method Summary
`MultivariateFunction` | `interpolate(double[][] xval, double[] yval)` Computes an interpolating function for the data set.

Method Detail

### interpolate

    MultivariateFunction interpolate(double[][] xval,
                                     double[] yval)

  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:
    `MathIllegalArgumentException` - if the arguments violate assumptions made by the interpolation algorithm.
    `DimensionMismatchException` - when the array dimensions are not consistent.
    `NoDataException` - if an array has zero-length.
    `NullArgumentException` - if the arguments are `null`.
