Update matrix_view.rs documentation

Fixed a (presumed) typo in documentation in matrix_view.rs.

Previously it says fixed_view and fixed_slice returns a matrix with `(RView, CView)` consecutive components. As per-input, and after re-reading the documentation and source code. Seems like RView and CView should be used instead of RView::dim() and CViem::dim().
