Functions
void	myra::qrt_inplace (const CMatrixRange< NumberS > &V, const CVectorRange< NumberS > &tau, const MatrixRange< NumberS > &T)
	Given a collection of scalar Householder reflectors [V,tau] from geqrf(), overwrites triu(T) to form the equivalent block reflector I-V*T*V'.
void	myra::qrt_inplace (const CMatrixRange< NumberD > &V, const CVectorRange< NumberD > &tau, const MatrixRange< NumberD > &T)
	Given a collection of scalar Householder reflectors [V,tau] from geqrf(), overwrites triu(T) to form the equivalent block reflector I-V*T*V'.
void	myra::qrt_inplace (const CMatrixRange< NumberC > &V, const CVectorRange< NumberC > &tau, const MatrixRange< NumberC > &T)
	Given a collection of scalar Householder reflectors [V,tau] from geqrf(), overwrites triu(T) to form the equivalent block reflector I-V*T*V'.
void	myra::qrt_inplace (const CMatrixRange< NumberZ > &V, const CVectorRange< NumberZ > &tau, const MatrixRange< NumberZ > &T)
	Given a collection of scalar Householder reflectors [V,tau] from geqrf(), overwrites triu(T) to form the equivalent block reflector I-V*T*V'.
void	myra::qrt_inplace (const MatrixRange< NumberS > &V, const CVectorRange< NumberS > &tau)
	Like qrt_inplace(V,tau,T), but overwrites triu(V). [Probably clobbering an R factor stored there].
void	myra::qrt_inplace (const MatrixRange< NumberD > &V, const CVectorRange< NumberD > &tau)
	Like qrt_inplace(V,tau,T), but overwrites triu(V). [Probably clobbering an R factor stored there].
void	myra::qrt_inplace (const MatrixRange< NumberC > &V, const CVectorRange< NumberC > &tau)
	Like qrt_inplace(V,tau,T), but overwrites triu(V). [Probably clobbering an R factor stored there].
void	myra::qrt_inplace (const MatrixRange< NumberZ > &V, const CVectorRange< NumberZ > &tau)
	Like qrt_inplace(V,tau,T), but overwrites triu(V). [Probably clobbering an R factor stored there].
Matrix< NumberS >	myra::qrt (const CMatrixRange< NumberS > &V, const CVectorRange< NumberS > &tau)
	Like qrt_inplace(), but returns T by value instead of overwriting it as an output argument.
Matrix< NumberD >	myra::qrt (const CMatrixRange< NumberD > &V, const CVectorRange< NumberD > &tau)
	Like qrt_inplace(), but returns T by value instead of overwriting it as an output argument.
Matrix< NumberC >	myra::qrt (const CMatrixRange< NumberC > &V, const CVectorRange< NumberC > &tau)
	Like qrt_inplace(), but returns T by value instead of overwriting it as an output argument.
