Vectorial - vector math library

Motivation

I couldn't find an open source math library that was usable and
supported simd - especially the ARM NEON variant.

Features

Supports NEON, SSE, scalar and generic gcc vector extension.
Most basic vector and matrix math is available, but not quite
yet full featured.

Design

Vectorial consists of two main parts, pure-C wrapper around
platform-specific vector instructions in the simd*.h files
and C++ classes for common uses, the vec*.h and mat*.h

The config.h autodetects approriate vector instructions to use.

The platform-specific support is done with intrisincs only,
allowing the compiler to have a full view of the code, hopefully
resulting in better optimizations especially with reordering etc.

Installation / Usage

Add vectorial/include to your include path

#include "vectorial/simd4f.h"  
for C-only simd wrapper, using it looks like this:
  simd4f v = simd4f_normalize( simd4f_add( simd4f_create(1,2,3,4), y) );
  float z = simd4f_get_z(v);

#include "vectorial/vectorial.h"
for C++ classes. They reside in vectorial namespace, you might
want to alias them to your own namespace
  namespace myproject {
    using namespace ::vectorial;
    // if you like different name: typedef vec3f Vector3;
  }
  using myproject::vec4f;
  
  vec4f v = normalize( vec4f(1,2,3,4) + y );
  float z = v.z();
