There is one prototype of gbsv
available, please see below.
gbsv( MatrixAB& ab, VectorIPIV& ipiv, MatrixB& b );
gbsv
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGBSV, DGBSV, CGBSV, and
ZGBSV. gbsv
computes
the solution to a complex system of linear equations A * X = B, where
A is a band matrix of order N with KL subdiagonals and KU superdiagonals,
and X and B are N-by-NRHS matrices.
The LU decomposition with partial pivoting and row interchanges is used to factor A as A = L * U, where L is a product of permutation and unit lower triangular matrices with KL subdiagonals, and U is upper triangular with KL+KU superdiagonals. The factored form of A is then used to solve the system of equations A * X = B.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixAB
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixAB>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
