Well, you're dealign with matrices and vector to do some linear algebra.
At some point it means you'll want to do some algebra
operations on them beside adding and multiplying them by scalar.
In this case, 99% of what you need exists in BLAS/LAPACK.
If you never do a matrix product nor a SVD or a LU decomposition, never
try to compute dot or external product, then you dont need a matrix, you
need a 2D array without any special semantic. And so this type needs to
be called array and not matrix nor vector.
