There is one prototype of gtsv
available, please see below.
gtsv( const int_t n, VectorDL& dl, VectorD& d, VectorDU& du, MatrixB& b );
gtsv
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGTSV, DGTSV, CGTSV, and
ZGTSV. gtsv
solves the
equation
A*X = B,
where A is an N-by-N tridiagonal matrix, by Gaussian elimination with partial pivoting.
Note that the equation A'*X = B may be solved by interchanging the order of the arguments DU and DL.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type VectorDL
.
The type of values is obtained through the value_type
meta-function typename value_type<VectorDL>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
