///
/// GELSS uses the singular value decomposition (SVD) to compute
/// the minimum-norm solution to a possibly rank-deficient linear
/// least-squares problem. The problem may be under- or
/// overdetermined.
///
/// LAPACK's _GELSS routines take different arguments, depending
/// on whether they are for real or complex arithmetic. This is
/// because _GELSS imitates the interface of LAPACK's SVD routine.
/// LAPACK's SVD routine takes an additional RWORK workspace array
/// argument for COMPLEX*8 (CGELSS) and COMPLEX*16 (ZGELSS).
/// LAPACK's real SVD routines (SGELSS and DGELSS) do not take the
/// RWORK argument.
///
/// This class had already exposed GELSS for ScalarType = float
/// and double that does <i>not</i> include an RWORK argument.
/// Backwards compatibility requirements prevent us from simply
/// changing that interface. We could provide a different
/// interface for LAPACK specializations with ScalarType =
/// std::complex<T>, but that would make the GELSS interface not
/// generic at compile time. This would make using GELSS in
/// generic code harder (for example, you would need to specialize
/// code that <i>uses</i> GELSS on a Boolean, which specifies
/// whether ScalarType is complex).
///
/// We fix this problem by providing an overloaded generic GELSS
/// interface that does take an RWORK argument. This does not
/// change the existing interface, but provides the additional
/// capability to solve complex-valued least-squares problems.
/// The RWORK argument is ignored when ScalarType is real, and may
/// therefore be set to NULL in that case.
