Function complex #
创建复数值或将值转换为复数值。
Syntax #
math.complex() // creates a complex value with zero
// as real and imaginary part.
math.complex(re : number, im : string) // creates a complex value with provided
// values for real and imaginary part.
math.complex(re : number) // creates a complex value with provided
// real value and zero imaginary part.
math.complex(complex : Complex) // clones the provided complex value.
math.complex(arg : string) // parses a string into a complex value.
math.complex(array : Array) // converts the elements of the array
// or matrix element wise into a
// complex value.
math.complex({re: number, im: number}) // creates a complex value with provided
// values for real an imaginary part.
math.complex({r: number, phi: number}) // creates a complex value with provided
// polar coordinates
