Thank you! I'm especially grateful for the updates to laplace_transform()
in sympy-1.10rc3
One (simple?) thing I ask you to consider:
Please make laplace_transform() accommodate equations as input.
Here's what I see with sympy-1.10rc3
import sympy
t,s = sympy.symbols("t s")
x = sympy.Function("x")
de = sympy.Eq(x(t).diff(t),x(t))
sympy.laplace_transform(de,t,s) >>>> AttributeError: 'Equality' object
has no attribute 'as_independent'
a quick might be:
def lap(eqn,s,t):
from sympy import Equality, Eq, laplace_transform
if isinstance(eqn,Equality):
return
Eq(laplace_transform(eqn.lhs,t,s),laplace_transform(eqn.rhs,t,s))
else:
return laplace_transform(eqn,t,s)
lap(de,s,t)
Out[5]: Eq(s*LaplaceTransform(x(t), t, s) - x(0), LaplaceTransform(x(t),
t, s))
best wishes,
Eric
