Functions
ComplexArray	ModuleBase::operator* (const double r, const ComplexArray &cd)
	Scale a ComplexArray cd by real r.
ComplexArray	ModuleBase::operator* (const std::complex< double > c, const ComplexArray &cd)
	Scale a ComplexArray cd by std::complex number c.
double	ModuleBase::abs2 (const ComplexArray &cd)
	Sum of absolute squares of all elements in cd.
std::complex< double >	ModuleBase::dot (const ComplexArray &cd1, const ComplexArray &cd2)
	Take "dot-product" of two ComplexArray: sum of cd1(conjugate)[i] * cd2[i].
void	ModuleBase::scale_accumulate (double r, const ComplexArray &cd1, ComplexArray &cd2)
	Does cd2 += r * cd1.
void	ModuleBase::scale_accumulate (std::complex< double > c, const ComplexArray &cd1, ComplexArray &cd2)
	Does cd2 += c * cd1.
void	ModuleBase::scaled_sum (double r1, const ComplexArray &cd1, double r2, const ComplexArray &cd2, ComplexArray &cd3)
	Does cd3 = r1*cd1 + r2*cd2.
void	ModuleBase::scaled_sum (std::complex< double > c1, const ComplexArray &cd1, std::complex< double > c2, const ComplexArray &cd2, ComplexArray &cd3)
	Does cd3 = c1*cd1 + c2*cd2.
void	ModuleBase::point_mult (ComplexArray &a1, ComplexArray &in2, ComplexArray &out)
	out[i] = a1[i] * in2[i]
template<class T >
void	ModuleBase::zeros (std::complex< T > *u, int n)
	set elements of u as zero which u is 1_d std::complex array
