gerqf

Prototype

There is one prototype of gerqf available, please see below.

gerqf( MatrixA& a, VectorTAU& tau );

Description

gerqf (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGERQF, DGERQF, CGERQF, and ZGERQF. gerqf computes an RQ factorization of a complex M-by-N matrix A: A = R * 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 1.196. Dispatching of gerqf

Value type of MatrixA	LAPACK routine
`float`	SGERQF
`double`	DGERQF
`complex<float>`	CGERQF
`complex<double>`	ZGERQF
