Dear all,
I am manipulating an IndexedBase object, and I would like to modify its
behavior when differentiated.
I thought to do something like this:
class custom(sy.IndexedBase):
def __init__(self, *args, **kwargs):
sy.IndexedBase.__init__(self, *args, **kwargs)
def diff(self, *args):
# Do some stuff
pass
However, when I initialize the object:
b = custom("b")
It gives the error:
object.__init__() takes no arguments
However, it works if I do:
b = sy.IndexedBase("b")
I have two questions:
1) How can I create an object derivated from IndexedBase?
2) Is my way of doing correct to redefine the behaviour of the derivative?
(It must work if I derivate a whole expression that contains the object)
Thanks for your attention,
Bests,
Lorenzo
