MATLAB Implementation of Cholesky Decomposition Algorithm for Scientific Computing Methods

Detailed Documentation

This article introduces the Cholesky decomposition algorithm in scientific computing methods and provides a MATLAB implementation. Cholesky decomposition factorizes a symmetric positive-definite matrix into the product of a lower triangular matrix and its transpose, commonly used for solving linear systems, matrix inversion, and random number generation. The MATLAB implementation utilizes built-in functions like chol() for efficient computation, with options for both upper and lower triangular factorizations. We will discuss the fundamental principles of Cholesky decomposition and provide a complete MATLAB program with detailed comments to help readers better understand and apply this algorithm. The code demonstrates practical applications including solving Ax=b systems and verifying decomposition accuracy through matrix reconstruction.
