求 Golang 中复数的共轭
Go 语言借助 cmplx 包，为复数的基本常数和数学函数提供内置支持。允许你借助数学/cmplx 包提供的 Conj()函数找到指定复数的共轭。因此，您需要在 import 关键字的帮助下，在程序中添加一个 math/cmplx 包来访问 Conj()函数。
语法:
func Conj(y complex128) complex128
让我们借助给定的例子来讨论这个概念:
例 1:
// Golang program to illustrate how to find
// conjugate of the given complex number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
// Finding conjugate of the
// specified complex number
// Using Conj() function
res_1 := cmplx.Conj(5i)
res_2 := cmplx.Conj(-1 + 12i)
res_3 := cmplx.Conj(-7 - 9i)
// Displaying the result
fmt.Printf("Result 1: %.1f", res_1)
fmt.Printf("\nResult 2: %.1f", res_2)
fmt.Printf("\nResult 3: %.1f", res_3)
}
输出:
Result 1: (0.0-5.0i)
Result 2: (-1.0-12.0i)
Result 3: (-7.0+9.0i)
例 2:
// Golang program to illustrate how to find
// conjugate of the given complex number
package main
import (
"fmt"
"math/cmplx"
)
// Main function
func main() {
cnumber_1 := complex(0, 2)
cnumber_2 := complex(1, 6)
// Finding conjugate of the
// given complex numbers
cvalue_1 := cmplx.Conj(cnumber_1)
cvalue_2 := cmplx.Conj(cnumber_2)
// Sum of the given values
res := cvalue_1 + cvalue_2
// Displaying results
fmt.Println("Complex Number 1: ", cnumber_1)
fmt.Printf("Conjugate 1: %.1f", cvalue_1)
fmt.Println("\nComplex Number 2: ", cnumber_2)
fmt.Printf("Conjugate 2: %.1f ", cvalue_2)
fmt.Printf("\nSum : %.1f", res)
}
输出:
Complex Number 1: (0+2i)
Conjugate 1: (0.0-2.0i)
Complex Number 2: (1+6i)
Conjugate 2: (1.0-6.0i)
Sum : (1.0-8.0i)
