Dear all,
So I'm trying to use Sympy to solve a simple system with indexed symbols,
something like this:
Eq 1.y[i] = sqrt(x[i])
Eq 2.m = Sum(z[i] * y[i], (i, 0, n)) / Sum(x[i], (i, 0, n))
where, *x, y, z, i, n and m* are symbols (x, y and z are *IndexedBase* and
Performance is a valid concern. We should definitely check that.
The __slots__ part I don't know. That could probably be done differently.
Regarding the implementation itself, how would you do it? The ability
to make Mul or Add do custom stuff for custom objects is a very
commonly requested
