std::conj(std::complex)
Defined in header <complex> | ? | ? |
|---|---|---|
template< class T > complex<T> conj( const complex<T>& z ); | (1) | ? |
std::complex<long double> conj( long double z ); | (2) | (since C++11) |
template< class DoubleOrInteger > std::complex<double> conj( DoubleOrInteger z ); | (3) | (since C++11) |
std::complex<float> conj( float z ); | (4) | (since C++11) |
计算复共轭成z通过倒转假想部分的符号。
%28，因为C++11%提供了29附加过载float，，，double，，，long double，以及所有整数类型，它们被视为零虚分量的复数。
参数
z | - | complex value |
|---|
返回值
复共轭z...
例
二次
#include <iostream>
#include <complex>
int main()
{
std::complex<double> z(1,2);
std::cout << "The conjugate of " << z << " is " << std::conj(z) << '\n'
<< "Their product is " << z*std::conj(z) << '\n';
}二次
产出：
二次
The conjugate of (1,2) is (1,-2)
Their product is (5,0)二次
