Complex is a lightweight framework designed for representing and working with complex numbers for iOS, macOS, tvOS, and watchOS.
Complex is available through CocoaPods, Carthage and the Swift Package Manager.
To install via CocoaPods, simply add the following line to your Podfile:
To install via Carthage, simply add the following line to your Cartfile:
To install via the Swift Package Manager add the following line to your
.package(url: "https://github.com/SomeRandomiOSDev/Complex.git", from: "1.0.0")
First import Complex at the top of your Swift file:
After importing, use of complex numbers is as simple as can be:
let input = Complex<Double>(real: 4.31, imaginary: 2.0) let scale = Complex<Double>(real: 1.5, imaginary: 2.718) let output = input * scale ...
The Complex type also has builtin functionality specific to complex numbers, such as conjugates and modulus/angle (for converting to polar coordinates):
let complex = Complex<Double>(real: 7.0, imaginary: -4.1) // Equal to 7.0 + 4.1i let conjugate = ~complex // or complex.conjugate() let (modulus, angle) = (complex.modulus, complex.angle) ...
The Swift library team has released their own Complex type as part of the Swift Numerics library. This library is likely to be archived in the future unless there is a continued need for this library to continue to be maintained. You can find more information about the new Complex type here
If you have need for a specific feature or you encounter a bug, please open an issue. If you extend the functionality of Complex yourself or you feel like fixing a bug yourself, please submit a pull request.
