| <div class="block">Computes a natural (also known as "free", "unclamped") cubic spline interpolation for the data set. |
| <p> |
| The <a href="../../../../../../org/apache/commons/math3/analysis/interpolation/SplineInterpolator.html#interpolate(double[], double[])"><code>interpolate(double[], double[])</code></a> method returns a <a href="../../../../../../org/apache/commons/math3/analysis/polynomials/PolynomialSplineFunction.html" title="class in org.apache.commons.math3.analysis.polynomials"><code>PolynomialSplineFunction</code></a> |
| consisting of n cubic polynomials, defined over the subintervals determined by the x values, |
| x[0] < x[i] ... < x[n]. The x values are referred to as "knot points."</p> |
| <p> |
| The value of the PolynomialSplineFunction at a point x that is greater than or equal to the smallest |
| knot point and strictly less than the largest knot point is computed by finding the subinterval to which |
| x belongs and computing the value of the corresponding polynomial at <code>x - x[i] </code> where |
| <code>i</code> is the index of the subinterval. See <a href="../../../../../../org/apache/commons/math3/analysis/polynomials/PolynomialSplineFunction.html" title="class in org.apache.commons.math3.analysis.polynomials"><code>PolynomialSplineFunction</code></a> for more details. |
| </p> |
| <p> |
| The interpolating polynomials satisfy: <ol> |
| <li>The value of the PolynomialSplineFunction at each of the input x values equals the |
| corresponding y value.</li> |
| <li>Adjacent polynomials are equal through two derivatives at the knot points (i.e., adjacent polynomials |
| "match up" at the knot points, as do their first and second derivatives).</li> |
| </ol></p> |
| <p> |
| The cubic spline interpolation algorithm implemented is as described in R.L. Burden, J.D. Faires, |
| <u>Numerical Analysis</u>, 4th Ed., 1989, PWS-Kent, ISBN 0-53491-585-X, pp 126-131. |
