New issue 3991 by [email protected]: Conjugate transpose of scalar
exponential treated like matrix
http://code.google.com/p/sympy/issues/detail?id=3991
Sympy doesn't seem to know that exponentiating a scalar results in another
scalar:
In [1]: from sympy import *
In [2]: beta = symbols('beta', complex=True)
In [3]: beta.conjugate().transpose()
Out[3]: conjugate(beta)
In [4]: exp(beta).conjugate().transpose()
Out[4]: transpose(exp(conjugate(beta)))
The result should simply be: exp(conjugate(beta))
Ran into this problem using the Dagger operation in sympy.physics.quantum,
where I got many instances of exp(I*alpha)*transpose(exp(-I*alpha)) that
should have simplified to 1 but instead had to be simplified by hand.
