The C++ standard doesn’t dictate exact implementation details for standard library classes, so it’s unsurprising that details of memory usage are missing from most references.

In this post:
- Fit a curve of degree N to a data set, getting data points 1 at a time.
- Storage Required: 3*N+2 values.
- Update Complexity: roughly 3*N+2 additions and multiplies.
- Finalize Complexity: Inverting a (N+1)x(N+1) matrix and multiplying by a vector to get polynomial coefficients.
- Simple C++ code and HTML5 demo at bottom!

It turns out the discrepancy was due to a typo in the original paper and not in the Boost.Accumulators implementation as I had originally suspected.
