Detailed Description

Function Documentation

syr2()

template<typename scalar_t >

void blas::impl::syr2	(	blas::Layout	layout,
		blas::Uplo	uplo,
		int64_t	n,
		scalar_t	alpha,
		scalar_t const *	x,
		int64_t	incx,
		scalar_t const *	y,
		int64_t	incy,
		scalar_t *	A,
		int64_t	lda
	)

Mid-level templated wrapper checks and converts arguments, then calls low-level wrapper.

LAPACK doesn't have [cz]syr2; this calls [cz]syr2k with k == 1, beta = 1.
