Package vecf32 provides common functions and methods for slices of float32

go get -u gorgonia.org/vecf32

This packagemath32. For testing this package usestestify/assert, which is licenced with aMIT/BSD-like licence

The point of this package is to provide operations that are accelerated by SIMD. However, this pakcage by default does not use SIMD. To use SIMD, build tags must be used. The supported build tags aresse andavx. Here's an example on how to use them:

• SSE - `go build -tags='sse' ...
• AVX - `go build -tags='avx' ...

This is mainly done to eliminate bounds checking in a loop. The idea is the bounds of the slice is checked early on, and if need be, panics early. Then if everything is normal, there won't be bounds checking while in the loop. This also means thatb must be at leastlen(a), otherwise a panic will occur.

To check for boundschecking and bounds check elimination (an amazing feature that landed in Go 1.7), compile your programs with-gcflags='-d=ssa/check_bce/debug=1'.
