Quaternion expression mapping a constant memory buffer.
| _Scalar | the type of the Quaternion coefficients |
| _Options | see class Map |
This is a specialization of class Map for Quaternion. This class allows to view a 4 scalar memory buffer as an Eigen's Quaternion object.

Constructs a Mapped Quaternion object from the pointer coeffs
The pointer coeffs must reference the four coefficients of Quaternion in the following order:
If the template parameter _Options is set to Aligned, then the pointer coeffs must be aligned.
