Function Documentation

scal()

template<typename T >

void blas::scal	(	int64_t	n,
		T	alpha,
		T *	x,
		int64_t	incx
	)

Scale vector by constant, \(x = \alpha x\).

Generic implementation for arbitrary data types.

Parameters

[in]	n	Number of elements in x. n >= 0.
[in]	alpha	Scalar alpha.
[in]	x	The n-element vector x, in an array of length (n-1)*incx + 1.
[in]	incx	Stride between elements of x. incx > 0.
