Can we ask questions on numerical analysis here? Prompted by the question: Approximation techniques for the square super-root function?
The comments on the question say:
Great question, but seemingly not DSP-related - may be better suited to e.g. math.stackexchange.com ? – Paul R
are you sure you meant to ask this in Signal processing? It's a good question, but I think it would be a better fit on math.SE. – yoda
While this could be on-topic on math.SE too, I see the interest of this question to signal processing people, where processor speed often is a limiting factor. – Tim
I see DSP literature dealing with these kinds of questions more often than pure mathematical literature. Any math references I could find would obviously be useful, but wouldn't necessarily have the implementation details of a more engineering-oriented approach. Questions like this one come up frequently when attempting to port DSP algorithms to embedded platforms, but the knowledge required for implementation isn't specific to any particular platform, and isn't strictly mathematical. That's my reasoning for the question, at least. – datageist
This is a numerical-methods question. As such, it can be asked on Stackoverflow as well as Math.SE. (And also one of the computational science sites if they are launched in the future.) Asking it on DSP in the hope that "some DSP people might know a better way of doing this thing which ought to be solved by experts of another discipline", may result in zero answers for a long time. – rwong
