MATLAB is widely used in academic and industrial settings for developing and prototyping Finite Element Analysis (FEA) codes due to its powerful matrix manipulation capabilities, built-in linear algebra solvers, and easy-to-use visualization tools. While commercial FEA packages (e.g., ANSYS, Abaqus) offer robust solutions, writing MATLAB .m files from scratch provides deep insight into the mathematical and computational foundations of the finite element method. matlab codes for finite element analysis m files
