How can I reverse rows/cols of a matrix or reverse a vector with nalgebra?

Question

How can I reverse rows/cols of a matrix or a vector as this is possible in Eigen3?

How can I reverseInPlace?

See the Eigen3 docs, quickref or reverse , reverseInPlace for comparison:

Vectors, rows, and/or columns of a matrix can be reversed (see DenseBase::reverse(), DenseBase::reverseInPlace(), VectorwiseOp::reverse()).

vec.reverse()           mat.colwise().reverse()   mat.rowwise().reverse()
vec.reverseInPlace()
