This library is a rewrite of the wright.c
file from Lawrence, Corless, and Jeffrey [1] in rust.
The Wright Omega function is defined as the solution to the equation ω + log(ω) = z
. It is a special case of the Lambert W function.
The library is available on crates.io and can be included in your project by adding the following to your Cargo.toml
file:
toml
[dependencies]
wright_omega = "0.1.0"
```rust use wrightomega::wrightomega; use wright_omega::Complex;
fn main() { let z = Complex::new(0.0, 0.0); let omega = wright_omega(z); println!("Wright Omega of {} is {}", z, omega); } ```
> Wright Omega of 0+0i is 0.5671433+0i
The library supports both f32
and f64
types. The f32
feature is enabled by default. To use f64
instead, add the following to your Cargo.toml
file:
toml
[dependencies]
wright_omega = { version = "0.1.0", features = ["f64"] }
Scipy uses the same implementation for Python. Matlab also has a built in implementation.
