##### sytrs

###### Prototype

There is one prototype of `sytrs` available, please see below.

    sytrs( const MatrixA& a, const VectorIPIV& ipiv, MatrixB& b );

###### Description

`sytrs` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SSYTRS, DSYTRS, CSYTRS, and ZSYTRS. `sytrs` solves a system of linear equations A*X = B with a complex symmetric matrix A using the factorization A = UD*U*T or A = LD*L*T computed by ZSYTRF.

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.

Table 1.295. Dispatching of sytrs

Value type of MatrixA | LAPACK routine
--- | ---
`float` | SSYTRS
`double` | DSYTRS
`complex<float>` | CSYTRS
`complex<double>` | ZSYTRS
