As you develop your script, the assembly process becomes the most critical phase. You will need to loop through each element to calculate the local stiffness matrix. In MATLAB, this is often done using numerical integration techniques like Gaussian quadrature. Once the local matrix is computed, you use the connectivity information to "scatter" these values into the global stiffness matrix. Efficient indexing is key here; using sparse matrix functions in MATLAB can significantly speed up the solution process for large-scale models. matlab codes for finite element analysis m files
