One imagines NDSolve does some form of preprocessing of the derivatives, which this precludes. Consequently vectorizing avoids the preprocessing but also doesn't enjoy the benefits when computing the derivatives. In my experience with complex expressions for the derivatives the net effect of vectorizing is longer solution times. A middle road like Simplify complex expressions with a time limit would be nice. But Simplify with TimeConstraint doesn't help. Ideas? | |
