示例1: testIntegralAndDerivative
void testIntegralAndDerivative(const Piecewise<F, BreakType>& piecewise, const Arg& value_at_start_time) {
// differentiate integral, get original back
auto piecewise_integral = integral(piecewise, value_at_start_time);
Piecewise<F, BreakType> piecewise_back = weakDerivative(piecewise_integral);
uniform_real_distribution<Arg> distribution(piecewise.domainStart(), piecewise.domainEnd());
Arg arg = distribution(engine);
valueCheck(piecewise(arg), piecewise_back(arg), 1e-8 * (Arg) 1);
valueCheck(value_at_start_time, piecewise_integral(piecewise.domainStart()), 1e-8 * (Arg) 1);
// check continuity at knot points
for (int i = 0; i < piecewise.numberOfSegments() - 1; ++i) {
const auto& f_this = (piecewise_integral.getSubfunction(i));
const auto& f_next = piecewise_integral.getSubfunction(i + 1);
valueCheck(f_this(piecewise_integral.segmentEnd(i) - piecewise_integral.segmentStart(i)), f_next(0.0), 1e-8 * (Arg) 1);
