Member Function Documentation

Disposable<Array> drift (const StochasticProcess &, Time t0, const Array & x0, Time dt) constReturns an approximation of the drift defined as $ mu(t_0 + Delta t, mathbf{x}_0) Delta t $.

Real drift (const StochasticProcess1D &, Time t0, Real x0, Time dt) const [virtual]Returns an approximation of the drift defined as $ mu(t_0 + Delta t, x_0) Delta t $.

Implements StochasticProcess1D::discretization.

Disposable<Matrix> diffusion (const StochasticProcess &, Time t0, const Array & x0, Time dt) constReturns an approximation of the diffusion defined as $ igma(t_0 + Delta t, mathbf{x}_0) qrt{Delta t} $.

Real diffusion (const StochasticProcess1D &, Time t0, Real x0, Time dt) const [virtual]Returns an approximation of the diffusion defined as $ igma(t_0 + Delta t, x_0) qrt{Delta t} $.

Implements StochasticProcess1D::discretization.

Disposable<Matrix> covariance (const StochasticProcess &, Time t0, const Array & x0, Time dt) constReturns an approximation of the covariance defined as $ igma(t_0 + Delta t, mathbf{x}_0)^2 Delta t $.

Real variance (const StochasticProcess1D &, Time t0, Real x0, Time dt) const [virtual]Returns an approximation of the variance defined as $ igma(t_0 + Delta t, x_0)^2 Delta t $.

Implements StochasticProcess1D::discretization.
