Works out of the box with OSX since CBLAS is included in the standard Accelerate framework. You might have to download and build LAPACK from source on other operating systems (LINUX: sudo apt-get libblas-dev
).

Double precision functions expect Float64Array
vectors, single precision functions expect Float32Array
vectors.
