There is one prototype of orgbr
available, please see below.
orgbr( const char vect, const int_t m, const int_t n, const int_t k, MatrixA& a, const VectorTAU& tau );
orgbr
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SORGBR and DORGBR. orgbr
generates one of the real orthogonal
matrices Q or P*T determined by DGEBRD when reducing
a real matrix A to bidiagonal form: A = Q * B * PT. Q and P*T are defined as products of elementary
reflectors H(i) or G(i) respectively.
If VECT = 'Q', A is assumed to have been an M-by-K matrix, and Q is of
order M: if m >= k, Q = H(1) H(2) . . . H(k) and orgbr
returns the first n columns of Q, where m >= n >= k; if m <
k, Q = H(1) H(2) . . . H(m-1) and orgbr
returns Q as an M-by-M matrix.
If VECT = 'P', A is assumed to have been a K-by-N matrix, and P*T is of order N: if k < n, PT = G(k) . . . G(2) G(1) and `orgbr` returns the first m rows of PT, where n >= m >= k; if k >= n, PT = G(n-1) . . . G(2) G(1) and `orgbr` returns P*T as an N-by-N matrix.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixA
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixA>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
