Usage

From source file:com.github.rinde.rinsim.scenario.generator.IntensityFunctions.java

/**
 * Compute the area of a sine intensity by using numerical approximation. The
 * range for which the area is computed is defined by a lower bound of
 * <code>0</code> and an upper bound of <code>length</code>.
 * @param s The intensity function to integrate.
 * @param lb The lower bound of the range.
 * @param ub The upper bound of the range.
 * @return The area./*  w  ww .java2  s  . c o m*/
 */
public static double areaByIntegration(IntensityFunction s, double lb, double ub) {
    final UnivariateIntegrator ri = new RombergIntegrator(16, 32);
    final double val = ri.integrate(10000000, asUnivariateFunction(s), lb, ub);
