Collaboration diagram for ModuleBase::vector_mul_real_op< T, Device >:

Public Types
using	Real = typename GetTypeReal< T >::type

Public Member Functions
void	operator() (const int dim, T *result, const T *vector, const Real constant)
	result[i] = vector[i] * constant, where vector is complex number and constant is real number。 It is different from the scal_op, which is used to multiply a complex number by a complex number.

operator()()

template<typename T , typename Device >

void ModuleBase::vector_mul_real_op< T, Device >::operator()	(	const int	dim,
		T *	result,
		const T *	vector,
		const Real	constant
	)

result[i] = vector[i] * constant, where vector is complex number and constant is real number。 It is different from the scal_op, which is used to multiply a complex number by a complex number.

Input Parameters

Parameters

dim	: array size
vector	: input array
constant	: input constant

Output Parameters

Parameters

result

: output array

Note

Use mulitple instead of divide. It is faster.
