说明：  用MATLAB实现的模态振型动画模拟，主要涉及到GUI中各控件的关联、模型网格绘制、各节点变形量颜色显示（第四维）、动画快速显示（如果可以，就把它称为第五维）等内容。
(By mode shape animation MATLAB to achieve, mainly related to the association of each GUI controls, draw a grid model, each node deformation colors (the fourth dimension), animation quickly display (if you can, put it called fifth dimension) and so on.)
