Armadillo is a C++ linear algebra library that provides matrix and vector operations. It is used for scientific and engineering applications, and it offers an easy-to-use and fast syntax for matrix and vector computations. Arma::Mat is a class in Armadillo, which represents a matrix of arbitrary size and type. Here are some code examples that demonstrate the usage of Arma::Mat:

**Example 1:** Creating a matrix

**Example 2:** Matrix multiplication

**Example 3:** SVD decomposition

#includeusing namespace arma; // Create a 3x3 matrix of double precision mat A(3,3); // Fill the matrix with random numbers A.randu();

#includeusing namespace arma; // Create two 3x3 matrices of double precision mat A(3,3); mat B(3,3); // Multiply the two matrices and store the result in C mat C = A * B;

#includeIn these examples, the Armadillo package library is used to perform linear algebra operations on matrices and vectors.using namespace arma; // Create a 3x3 matrix of double precision mat A(3,3); // Fill the matrix with random numbers A.randu(); // Perform SVD decomposition mat U, S, V; svd(U, S, V, A);
