- - ### Method Detail

    - #### interpolate

          MultivariateFunction interpolate(double[][] xval,
                                         double[] yval)
                                           throws MathIllegalArgumentException,
                                                  DimensionMismatchException,
                                                  NoDataException,
                                                  NullArgumentException

      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`.
