Generalized Hessenberg Matrices
that the property of being generalized Hessenberg matrix is preserved by post- and premultiplication by a nonsingular upper triangular matrix, by inversion (for invertible matrices), etc. We also study a special kind of ge...

Givens' reduction of quaternion-valued matrices to upper Hessenberg form
The number of real operations necessary to reduce a quaternion-valuedmatrix into a similar upper Hessenberg matrix by making use of quaternion-valued Givens' transformation matrices is relatively large. Two possibilities of how to r...

Fast Givens transformation for quaternion-valued matrices applied to Hessenberg reduction
The Fast Givens' transformation, known for the real case, can also be defined for quaternion valued matrices, in particular, a reduction to upper Hessenberg form of general quaternion valued matrices is presented, including a numerical examp...
