Comment #7 on issue 2723 by [email protected]: What should summation() do with non-integer limits?
http://code.google.com/p/sympy/issues/detail?id=2723
When working with spin, I've been using the m_values method in the spin module, for a given j, it returns the number of possible spin values and a list of them, so
In [1]: from sympy.physics.quantum.spin import m_values In [2]: m_values(1) Out[2]: (3, [1, 0, -1]) In [3]: m_values(S(3)/2) Out[3]: (4, [3/2, 1/2, -1/2, -3/2]) When you call it, you can do something like: size, mvals = m_values(j) Then you can either iterate over the size variable or the m values directly. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
