Add support for Complex64 matrix exponentials?

[rootware]

Hi all,
Thank you so much for this crate, it's much needed in the ecosystem! Have a feature request: would it be possible to extend the functionality in this crate (esp for calculating matrix exponentials) to support not just f64 but also Complex64/c64 matrices? A lot of the matrix exponential functionality as well as integrators you have developed have amazing applications in quantum physics (especially exp(A t) calculations), except a lot of the time we're working with complex numbers instead just floats.

I couldn't find any other stable matrix exponentials for complex numbers in the Rust ecosystem, and especially none using faer so there's definitely a need in the ecosystem 🙂
Thank you!

Thank you for the suggestion! Yes, this is on my radar. I'm currently going through the code to add generics to all our methods - for me, I want to support both f32 and f64. The plan is eventually to support f32, f64, c32, c64, ... throughout the crate. At the moment, my focus is on some new matrix-free matexp*vec methods for large (real) sparse systems, so it may take some time to circle back to this.
