 Several standard linear algebra operations are provided for the matrix and vector.

 For types that lapack do not use, a generic version of the matrix product is provided.
 (same syntax, the dispatch is made at compile time depending of the type of the matrices).
 
-NB : 
-
-* The **generic** version of the product will be used if
-both matrices do not have the same type.
-**Is this reasonnable ??**.
-
-* Is the matrix's slowest index is not contiguous, blas/lapack can not be called directly.
-  So a temporary copy will be made to reorganize the matrix before calling blas/lapack.
-  Code is therefore (normally !) always correct, but this can produce a serious performance hit.
