brainpy.dyn.base.DSView#

class brainpy.dyn.base.DSView(target, index, varshape=None, name=None, mode=None)[source]#

DSView, an object used to get a view of a dynamical system instance.

It can get a subset view of variables in a dynamical system instance. For instance,

>>> import brainpy as bp
>>> hh = bp.dyn.HH(10)
>>> bp.dyn.DSView(hh, slice(5, 10, None))
>>> # or, simply
>>> hh[5:]
