There is one prototype of sysv
available, please see below.
sysv( MatrixA& a, VectorIPIV& ipiv, MatrixB& b );
sysv
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSYSV, DSYSV, CSYSV, and
ZSYSV. sysv
computes
the solution to a complex system of linear equations A * X = B, where
A is an N-by-N symmetric matrix and X and B are N-by-NRHS matrices.
The diagonal pivoting method is used to factor A as A = U * D * U*T, if UPLO = 'U', or A = L * D * L*T, if UPLO = 'L', where U (or L) is a product of permutation and unit upper (lower) triangular matrices, and D is symmetric and block diagonal with 1-by-1 and 2-by-2 diagonal blocks. 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.
