Hi, I have a system of recurrent relationships, like the following (simplified example):
a = Function('a') b = Function('b') k = Symbol('k', integer=True) a(k+1) == b(k+1,k)*a(k) + 2*b(k+1,k) b(k+2,k) == b(k+2,k+1)*b(k+1,k) Is it possible to give these to SymPy and have it automatically figure out what (a(k+n) - a(k)) would look like for some arbitrary integer n? I don't know what this operation is called in SymPy terms, so no idea where to start... Thanks! -- You received this message because you are subscribed to the Google Groups "sympy" group.
