Dear support,
I'm giving a talk Wednesday and would like to do the following
interact as an example of how easy interacts are:
y = var('y')
@interact
def _(g=input_box(default = 1-y)):
P=plot_slope_field(g,(x,0,3),(y,0,20))
y = function('y',x)
f = desolve(diff(y,x) + g, y, ics=[2,2])
Q=plot(f,0,3)
show(P+Q)
Only it isn't easy. The declaring of y = function('y',x), which is
necessary to use desolve, causes the following error:
UnboundLocalError: local variable 'y' referenced before assignment
And the 'g' in the desolve also causes problems shortly thereafter. I
tried a lot of things to fix this, but nothing seemed to work quite
right. Note that this works nicely without interact.
Any help one can give in a relatively timely basis would be much
appreciated! Thanks in advance,
- kcrisman
