Function complex

Create a complex value or convert a value to a complex value.

Syntax

complex()                           // creates a complex value with zero
                                         // as real and imaginary part.
complex(re : number, im : string)   // creates a complex value with provided
                                         // values for real and imaginary part.
complex(re : number)                // creates a complex value with provided
                                         // real value and zero imaginary part.
complex(complex : Complex)          // clones the provided complex value.
complex(arg : string)               // parses a string into a complex value.
complex(array : Array)              // converts the elements of the array
                                         // or matrix element wise into a
                                         // complex value.
complex({re: number, im: number})   // creates a complex value with provided
                                         // values for real an imaginary part.
complex({r: number, phi: number})   // creates a complex value with provided
                                         // polar coordinates

Examples

var a = complex(3, -4);     // a = Complex 3 - 4i
a.re = 5;                        // a = Complex 5 - 4i
var i = a.im;                    // Number -4;
var b = complex('2 + 6i');  // Complex 2 + 6i
var c = complex();          // Complex 0 + 0i
var d = add(a, b);          // Complex 5 + 2i
