But the original *does* evaluate at positive PI.
print(f(pi))
# 0
This is a bug.

This, unfortunately.

You received this message because you are subscribed to the Google Groups

To unsubscribe from this group and s
like basically, why don't the piecewise functions collapse to scalars? This
should result in the same output, no?
M_vec(x) = vector([M_Tx(x), M_by(x), M_bz(x)]).column()
M_vec(x = l1)
M_vec_l1 = vector([M_Tx(l1), M_by(x=l1), M_bz(x=l1)]).column()
M_vec_l1
gives instead

Is there something better? I tried to get piecewise to work, but I
couldn't plot, integrate, etc., the function.

Ah, I see. If there was were primitive functions for LessThan(x,y),
Equal(x,y), and GreaterThan(x,y), and they returned 0 or 1, I think
that's all I would need:
f(x,y) = y + LessThan(x,pi/2)*f1(x) + Equal(x,pi/2)*f2(x) + Gre

I wasn't aware of piecewise(), and although it doesn't seem as elegant
or flexible as being able to use Indicator functions in my function
definitions, I think it sho
Are you aware of the function piecewise(), which seems to do what you

I don't think composition of piecewise functions has been implemented yet.
