There is one prototype of geqp3
available, please see below.
geqp3( MatrixA& a, VectorJPVT& jpvt, VectorTAU& tau );
geqp3
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGEQP3, DGEQP3, CGEQP3, and
ZGEQP3. geqp3
computes
a QR factorization with column pivoting of a matrix A: A*P = Q*R using
Level 3 BLAS.
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.
