##### orglq

###### Prototype

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

    orglq( MatrixA& a, const VectorTAU& tau );

###### Description

`orglq` (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SORGLQ and DORGLQ. `orglq` generates an M-by-N real matrix Q with orthonormal rows, which is defined as the first M rows of a product of K elementary reflectors of order N

Q = H(k) . . . H(2) H(1)

as returned by DGELQF.

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 1.197. Dispatching of orglq

Value type of MatrixA | LAPACK routine
--- | ---
`float` | SORGLQ
`double` | DORGLQ
