Stochastic Differential Equations
热度 1 王伟华 2010-1-11 21:58
Non-stochastic differential equations are models of dynamical systems where the state evolves continuously in time. If they are autonomous, then the state's future values depend only on the present state; if they are non-autonomous, it is allowed to depend on an exogeneous driving term as w ...
