Abstract: The field of matrix conditioning plays a crucial role in enhancing the numerical stability and accuracy of computational algorithms, partic- ularly when dealing with ill-conditioned matrices. This paper explores various techniques for transforming ill-conditioned matrices into well-conditioned ones, focusing on methods such as regularization, preconditioning, scaling, and orthogonalization. Through a detailed literature review, we examine key algorithms and their effectiveness in addressing numerical instability in linear systems, eigenvalue problems, and regression models. Special attention is given to the application of matrix conditioning in computational mathematics, machine learning, and numerical optimization. Additionally, we discuss the challenges encountered when applying these techniques to real-world problems, particularly in large-scale computations and sparse systems. The study provides an in-depth analysis of the stability and convergence of iterative methods, precon ditioned Krylov subspace methods, and randomized algorithms, highlighting their roles in improving matrix conditioning. We conclude with an evaluation of the practical implications and potential fu ture developments in matrix conditioning methods, suggesting areas for further research to enhance the computational efficiency and reliability of numerical algorithms in a variety of scientific and engineering applications.
