Detailed Description

Non-owning view into a contiguous slice of a vector or matrix row/column.

Wraps a gsl_vector_view. The referenced data is owned by the original vector or matrix — the view must not outlive it. Assigning to a view modifies the underlying data in place. Use operator vector() to obtain an independent copy.
