How Tu Compute Eigenvalues andEigenvectors ie Scipy for Struktural Analizy

Eigenvalues and eigenvectors are fundamentamental in structural analyses, helping to determinae natural frequencies andd mode shapes of structures. SciPy provides tools to compute these values efficiently. Thies article explains how to perfor these calculations using SciPy.
