采用有限单元法计算平面刚架自振频率，可生成单刚、单元质量阵并组成总刚、总质量矩阵，并绘图显示。(Plane frame using the finite element method to calculate the natural frequency can be generated just a single unit consisting of the total mass matrix and just total mass matrix, and graphics.)

说明：  This work proposes two novel optimization algorithms called Salp Swarm Algorithm (SSA) and Multiobjective Salp Swarm Algorithm (MSSA) for solving optimization problems with single and multiple objectives. The main inspiration of SSA and MSSA is the swarming behaviour of salps when navigating and foraging in oceans. These two algorithms are tested on several mathematical optimization functions to observe and confirm their effective behaviours in finding the optimal solutions for optimization problems.
