#includeIn this example, we create a FloatMatrix A with size 3x3 and assign it values. We then perform an LU decomposition on A, which decomposes A into two new matrices L and U. We print these matrices to the console. Package library: FloatMatrix is not a standard C++ library. It appears to be a custom library created by the author of the code examples.#include "FloatMatrix.h" int main() { FloatMatrix A(3, 3); A(0, 0) = 1.0; A(0, 1) = 2.0; A(0, 2) = 3.0; A(1, 0) = 4.0; A(1, 1) = 5.0; A(1, 2) = 6.0; A(2, 0) = 7.0; A(2, 1) = 8.0; A(2, 2) = 9.0; FloatMatrix L; FloatMatrix U; A.LU(L, U); std::cout << "L = \n" << L << "\n"; std::cout << "U = \n" << U << "\n"; }
