Linear Algebra for Rust and Examples (3) Parallel Linear Solver
To use the multi-frontal solver in a parallel fashion, you can use the rayon crate to parallelize the factorization and solution steps of the solver. Here is an example in Rust: This code creates a random sparse 3×3 matrix A with approximately 50% non-zero elements and a random 3D vector B, and then solves the…

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…

Inverse Matrix Features for Eigen3 -(2) Multifrontal Solvers and Parallization using OpenMP
You can use the multifrontal solver in Eigen to solve linear systems of equations involving dense matrices. The multifrontal solver is a direct solver that uses the multifrontal method to factorize the coefficient matrix and solve the linear system. Here is an example of how you can use the multifrontal solver in Eigen: You can…
