register(name, stateupdater)	Register a state updater.

Details

abstract __call__(equations, variables=None, method_options=None)

Generate abstract code from equations. The method also gets the the variables because some state updaters have to check whether variable names reflect other state variables (which can change from timestep to timestep) or are external values (which stay constant during a run) For convenience, this arguments are optional – this allows to directly see what code a state updater generates for a set of equations by simply writing euler(eqs), for example.

static apply_stateupdater(equations, variables, method, method_options=None, group_name=None)

Applies a given state updater to equations. If a method is given, the state updater with the given name is used or if is a callable, then it is used directly. If a method is a list of names, all the methods will be tried until one that doesn’t raise an UnsupportedEquationsException is found.

static register(name, stateupdater)

Register a state updater. Registered state updaters can be referred to via their name.
