Searched, but little was found. I just want to know more about the rational of defining this union of different kinds of vectors. Thanks.

See here: [http://docs.julialang.org/en/latest/manual/arrays.html#Implementation-1](http://docs.julialang.org/en/latest/manual/arrays.html#Implementation-1).

> `StridedVector` and `StridedMatrix` are convenient aliases defined to make it possible for Julia to call a wider range of BLAS and LAPACK functions by passing them either Array or SubArray objects, and thus saving inefficiencies from memory allocation and copying.

It now also include reshapes.

Ah, I see. Thanks a lot for the pointer!
