Hi Fellow Gophers I wonder what is the canonical Go library for finding roots of single-valued real functions?
In particular, I am finding an implementation of Brent's method <https://en.wikipedia.org/wiki/Brent's_method>. Brent's method is the default algorithm in R, Matlab, and Scipy <https://docs.scipy.org/doc/scipy/reference/generated/scipy.optimize.root_scalar.html#scipy.optimize.root_scalar> . Gonum has a pretty comprehensive list of facilities for optimization <https://pkg.go.dev/gonum.org/v1/gonum@v0.15.1/optimize>, but I couldn't find one that does simple root finding. There seem to be two packages out there that implement Brent's method, but they are of dubious provenance: * https://pkg.go.dev/github.com/cpmech/gosl/num#Brent . Relies on the derivative of f, f'(x), which shouldn't be the case for Brent's method. Plus, it pulls in a deluge of dependencies, and is not in pure Go. * https://pkg.go.dev/go.skia.org/infra/pinpoint/go/compare/stats . The zeroin function is not even exported, so presumably of unknown quality. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
