Comment (by lftabera):
This will not work, the elements of the array might be arrays
{{{
sage: var('x,y')
(x, y)
sage: x1=y
sage: y1=-x
sage: A=desolve_odeint([x1,y1],[-0.5,0.3],srange(0,1,0.01),[x,y])
sage: list_plot(A,plotjoined=True)
TypeError Traceback (most recent call
last)
...
TypeError: unable to coerce to a ComplexNumber: <type 'numpy.ndarray'>
}}}
Th erecommended way for lists tuples etc. would have been
{{{
if not data:
return Grpahics()
}}
But this does not work with ndarrays. len is O(1) for these types.
