public PolynomialSplineFunction interpolate(double[] x,
                                            double[] y)
                                     throws DimensionMismatchException,
                                            NumberIsTooSmallException,
                                            NonMonotonicSequenceException

Computes a linear interpolating function for the data set.

Specified by:

interpolate in interface UnivariateInterpolator

Parameters:

x - the arguments for the interpolation points

y - the values for the interpolation points

Returns:

a function which interpolates the data set

Throws:

DimensionMismatchException - if x and y have different sizes.

NonMonotonicSequenceException - if x is not sorted in strict increasing order.

NumberIsTooSmallException - if the size of x is smaller than 2.
