SDE.source_dw(dw=None, corr=None, rho=None)[source]¶

Setup a source of standard Wiener process (Brownian motion) increments, to be used as ‘dw’ during integration.

Parameters:	dw : source, or source subclass, or None If an object complying with the `source` protocol, it is returned (`corr` and `rho` are ignored). If a source subclass, it is instantiated with the given parameters, and returned. If None, a new instance of `wiener_source` is returned, with the given parameters. corr, rho : see `wiener_source` documentation
Returns:	An object complying with the `source` protocol, instantiating the requested stochasticity source. The shape of source values is set to `wshape`.
