Class SplineInterpolatorTest

java.lang.Object
  org.apache.commons.math3.analysis.interpolation.SplineInterpolatorTest

public class SplineInterpolatorTest
extends Object
extends Object

Test the SplineInterpolator.

Version:: $Id: SplineInterpolatorTest.java 1364030 2012-07-21 01:10:04Z erans $

Field Summary
`protected double`	`coefficientTolerance` error tolerance for interpolating polynomial coefficients
`protected double`	`interpolationTolerance` error tolerance for interpolated values -- high value is from sin test
`protected double`	`knotTolerance` error tolerance for spline interpolator value at knot points

Constructor Summary
`SplineInterpolatorTest()`

Method Summary
`void`	`testIllegalArguments()`
`void`	`testInterpolateLinear()`
`void`	`testInterpolateLinearDegenerateThreeSegment()`
`void`	`testInterpolateLinearDegenerateTwoSegment()`
`void`	`testInterpolateSin()`
`protected void`	`verifyConsistency(PolynomialSplineFunction f, double[] x)` Verifies that interpolating polynomials satisfy consistency requirement: adjacent polynomials must agree through two derivatives at knot points
`protected void`	`verifyInterpolation(UnivariateFunction f, double[] x, double[] y)` verifies that f(x[i]) = y[i] for i = 0..n-1 where n is common length.
