BDSQR computes the singular value decomposition (SVD) of a n-by-n bidiagonal matrix B.

The SVD of B has the following form:
B = Ub * S * Vb'

::

B = Ub * S * Vb'

where
• S is the n-by-n diagonal matrix of singular values of B
• the columns of Ub are the left singular vectors of B
• the columns of Vb are its right singular vectors

* S is the n-by-n diagonal matrix of singular values of B

* the columns of Ub are the left singular vectors of B

* the columns of Vb are its right singular vectors

The computation of the singular vectors is optional; this function accepts input matrices U (of size nu-by-n) and V (of size n-by-nv) that are overwritten with U*Ub and Vb’*V. If nu = 0 no left vectors are computed; if nv = 0 no right vectors are computed.
