Vector functions (double)

Optimized vector products, norm and absolute value.

The MATLAB toolbox offers two particular functions working on vectors as the vector cross product and the dot product. These functions are implemented to work on a general matrix dimension. Unfortunately, this implies a long overhead and slows down the performance significantly.

This archive offers some particular vector functions as the vector norm, the vector length, scaling and the cross respectively dot product. All functions work on the first dimension of [3xM] double matrices.
