after some steps in Mathematica, my script currently generates an output equation with different variables u, v, w, and so on that each depend on the parameters (n, k, j), e.g. u[n,k,j]. When calculating at point (n,k,j), all values from before are known, meaning I can access u[n-1,k,j] and u[n,k-1,j] etc...
I would like Mathematica to sort my equation by putting known values to one side and unknown ones to the other side of the equal sign. I didn't find any appropriate command to do that. Can somebody help me with an approach?
