该matlab程序为平面桁架的有限元分析程序，输入节点，单元，载荷信息就可以得到节点位移，节点荷载以及单元位移，内力，应力等结果。对刚度矩阵采用的方法是对角元乘大数法。程序注释文字清楚，准确。(The matlab program is a finite element analysis program for plane truss. The input node, element and load information can be used to get the results of nodal displacement, nodal load, element displacement, internal force, stress and so on. The method of stiffness matrix is diagonal element multiplied by large number. Program comments text clear and accurate.)
