Standard MATLAB matrices are dense. For 3D problems with thousands of elements, storing a full $K$ matrix consumes excessive memory. Advanced M-files utilize the sparse command. material properties (Young's modulus)

: Reviewers note that while using functions like eig for eigenpairs is correct for small matrices, it becomes computationally expensive for larger systems where eigs would be preferred. fprintf('Number of Elements: %d\n'
