Quaternion singular value decomposition based on bidiagonalization to a real or complex matrix using quaternion Householder transformations

We present a practical and efficient means to compute the singular value decomposition (SVD) of a real or complex quaternion matrix A based on bidiagonalization of A to a real or complex bidiagonal matrix B using quaternionic Householder transformations. Computation of the SVD of B using an existing subroutine library such as lapack provi...More
