Just a question: We currently only have indexed derivatives by indexed objects:
>>> A[i].diff(A[j]) KroneckerDelta(i, j) But, does it make sense to derive an indexed symbol by the index? >>> A[i].diff(i) A[1] >>> A[i**2].diff(i) A[2*i] Currently the aforementioned operations return 0. I thought we could add this kind of operation, but I'm not sure if it makes sense. Indices are supposed to be integers, but indices can also be any kind of expression. -- You received this message because you are subscribed to the Google Groups "sympy" group.
