Constructor Detail

ComplexUnivariateIntegrator

public ComplexUnivariateIntegrator(UnivariateIntegrator integrator)

Crate a complex integrator from a real integrator.

Parameters:

integrator - underlying real integrator to use

Method Detail

integrate

public Complex integrate(int maxEval,
                         CalculusFieldUnivariateFunction<Complex> f,
                         Complex start,
                         Complex end)

Integrate a function along a straight path between points.

Parameters:

maxEval - maximum number of evaluations (real and imaginary parts are evaluated separately, so up to twice this number may be used)

f - the integrand function

start - start point of the integration path

end - end point of the integration path

Returns:

the value of integral along the straight path

integrate

public Complex integrate(int maxEval,
                         CalculusFieldUnivariateFunction<Complex> f,
                         Complex start,
                         Complex... path)

Integrate a function along a polyline path between any number of points.

Parameters:

maxEval - maximum number of evaluations (real and imaginary parts are evaluated separately and each path segments are also evaluated separately, so up to 2n times this number may be used for n segments)

f - the integrand function

start - start point of the integration path

path - successive points defining the path vertices

Returns:

the value of integral along the polyline path
