##### gelqf

###### Prototype

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

    gelqf( MatrixA& a, VectorTAU& tau );

###### Description

`gelqf` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGELQF, DGELQF, CGELQF, and ZGELQF. `gelqf` computes an LQ factorization of a complex M-by-N matrix A: A = L * Q.

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 1.192. Dispatching of gelqf

Value type of MatrixA | LAPACK routine
--- | ---
`float` | SGELQF
`double` | DGELQF
`complex<float>` | CGELQF
`complex<double>` | ZGELQF
