There is one prototype of gesv
available, please see below.
gesv( MatrixA& a, VectorIPIV& ipiv, MatrixB& b );
gesv (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGESV, DGESV, CGESV, and
ZGESV. gesv computes
the solution to a complex system of linear equations A * X = B, where
A is an N-by-N matrix 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 = P * L * U, where P is a permutation matrix, L is unit lower triangular, and U is upper triangular. 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 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.
