There is one prototype of posv
available, please see below.
posv( MatrixA& a, MatrixB& b );
posv (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SPOSV, DPOSV, CPOSV, and
ZPOSV. posv computes
the solution to a complex system of linear equations A * X = B, where
A is an N-by-N Hermitian positive definite matrix and X and B are N-by-NRHS
matrices.
The Cholesky decomposition is used to factor A as A = U*H U, if UPLO = 'U', or A = L * L**H, if UPLO = 'L', where U is an upper triangular matrix and L is a lower triangular matrix. 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.
