Expression of the reverse of a vector or matrix.
- Parameters:
-
| MatrixType | the type of the object of which we are taking the reverse |
This class represents an expression of the reverse of a vector. It is the return type of MatrixBase::reverse() and VectorwiseOp::reverse() and most of the time this is the only way it is used.
- See also:
- MatrixBase::reverse(), VectorwiseOp::reverse()
