                                                                double[] yval,

      Compute an interpolating function for the dataset.
      Specified by:
        `interpolate` in interface `BivariateGridInterpolator`
      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.
        `fval` - The values of the interpolation points on all the grid knots: `fval[i][j] = f(xval[i], yval[j])`.
      Returns:
        a function which interpolates the dataset.
      Throws:
        `DimensionMismatchException` - if the array lengths are inconsistent.
        `NoDataException` - if any of the arrays has zero length.
        `NonMonotonicSequenceException` - if the array is not sorted.
        `NullArgumentException`
