Websdeint is a collection of numerical algorithms for integrating Ito and Stratonovich stochastic ordinary differential equations (SODEs). It has simple functions that can be used in a … WebIto integral is a martingale, but t is not. Thus we see that applying a functional operation to a process which is an Ito integral we do not necessarily get another Ito integral. But there is a natural generalization of Ito integral to a broader family, which makes taking functional operations closed within the family. Definition 1.
