The huge mememory consumption of julia code for our project of fractional Chern insulator once pushed me to rust. The smooth conversion between these two languages really surprise me, probably due to the modern desgin of rust syntax.

However, I have to say that playing with complex numbers and tensors in rust is almost a nightmare, due to the ugly design of the interfraces for the current implementation of linear algebra libs, including

• nalgebra
• ndarray-linalg

I really want a user-friendly linear algebra like julia (which I assume to be the best among all programming languages, particularly far exceeding the famous numpy), so want to desgin one myself.
