How do you inverse complex matrix with Armadillo linear algebra library? - Answers

To invert a complex matrix using the Armadillo linear algebra library, you can utilize the inv() function, which computes the inverse of a matrix. First, ensure you include the Armadillo header and link against the library. Here's a simple example: #include <armadillo> arma::cx_mat A = {{1.0, 2.0}, {3.0, 4.0}}; // Define a complex matrix arma::cx_mat A_inv = inv(A); // Invert the matrix Make sure the matrix is square and non-singular for the inversion to be valid.
