clenshaw_evaluate() #2

Closed RJDennis closed 7 years ago

RJDennis commented 7 years ago

Beyond the one dimensional case, the clenshaw_evaluate() functions are slow and use too much memory.

The poor performance is due to temporaries created to store intermediate-weights (p, basically). I cannot see an easy way to avoid this.
