There is one prototype of largv
available, please see below.
largv( const int_t n, VectorX& x, VectorY& y, VectorC& c );
largv (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SLARGV, DLARGV, CLARGV, and
ZLARGV. largv generates
a vector of complex plane rotations with real cosines, determined by
elements of the complex vectors x and y. For i = 1,2,...,n
( c(i) s(i) ) ( x(i) ) = ( r(i) ) ( -conjg(s(i)) c(i) ) ( y(i) ) = ( 0 )
where c(i)*2 + ABS(s(i))*2 = 1
The following conventions are used (these are the same as in ZLARTG, but differ from the BLAS1 routine ZROTG): If y(i)=0, then c(i)=1 and s(i)=0. If x(i)=0, then c(i)=0 and s(i) is chosen so that r(i) is real.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type VectorX.
The type of values is obtained through the value_type
meta-function typename value_type<VectorX>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
