There is one prototype of gelss
available, please see below.
gelss( MatrixA& a, MatrixB& b, VectorS& s, const Scalar >, int_t& rank );
gelss
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGELSS, DGELSS, CGELSS, and
ZGELSS. gelss
computes
the minimum norm solution to a complex linear least squares problem:
Minimize 2-norm(| b - A*x |).
using the singular value decomposition (SVD) of A. A is an M-by-N matrix which may be rank-deficient.
Several right hand side vectors b and solution vectors x can be handled in a single call; they are stored as the columns of the M-by-NRHS right hand side matrix B and the N-by-NRHS solution matrix X.
The effective rank of A is determined by treating as zero those singular values which are less than RCOND times the largest singular value.
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.
