numpy2go
This is a simple example of how to write a go libary (shared object) with exported functions that can accept numpy arrays as passed by ctypes. It requires go 1.5.
To try it run:
go build -buildmode=c-shared -o numpy2go.so
python numpy2go.pyWhich should output:
Python says [ 0. 1. 2.]
Go says [0 1 2]
