Detailed Description

template<typename XprType>
class Eigen::CommaInitializer< XprType >

Helper class used by the comma initializer operator.

This class is internally used to implement the comma initializer feature. It is the return type of MatrixBase::operator<<, and most of the time this is the only way it is used.

Member Function Documentation

XprType& finished ( )
inline
Returns
the built matrix once all its coefficients have been set. Calling finished is 100% optional. Its purpose is to write expressions like this:
quaternion.fromRotationMatrix((Matrix3f() << axis0, axis1, axis2).finished());
