Linear Algebra for Rust and Examples (2) Inverse Matrix and Linear Solver
Here is an example of how to compute the inverse of a 2×2 matrix using the nalgebra library in Rust: The try_inverse method computes the inverse of the matrix, if it exists. If the matrix is singular (i.e., not invertible), it returns None. The unwrap method is used to extract the inverse from the Option…
