Values are stored in a one-dimensional array, in row-major order. Compatibility with bidimensional arrays, however, has been preserved.
Most methods respect immutability at the cost of extra allocations. Methods like MultiplyAdd(DVector, Double, DVector) save unneeded allocations. Most methods are hardware accelerated, either by using managed references, SIMD operations or both. Memory pinning has also been reduced to the minimum.
