非线性动力学-分岔图-matlab-程序，弹簧质量系统在简谐激励作用下的的首破振动(Nonlinear dynamics- bifurcation diagram-Matlab-program, the spring mass system under harmonic excitation is broken vibration)

读入COMSOL软件所生成的二维mphtxt三角形网格文件，读入相关网格的节点、三角形单元，边界信息。调用此函数时应将包含相关的路径与文件名的字符串作为输入参数。包 中包含了一个m函数文件与一个示例网格数据文件。 (read the information of 2-d triangle mesh file--*.mphtxt generated by COMSOL. The input parameter is the path and name of mesh file. A matlab source file and mesh file is included in it.)

说明：  “模拟退火”算法是源于对热力学中退火过程的模拟，在某一给定初温下，通过缓慢下降温度参数，使算法能够在多项式时间内给出一个近似最优解。利用模拟退火算法,基于最优下料编码方式,对矩形件进行下料处理。("Simulated annealing" algorithm is derived from the simulation of the annealing process in thermodynamics. At a given initial temperature, the algorithm can give an approximate optimal solution in polynomial time by slowly decreasing the temperature parameter. Based on optimal blanking coding method, simulated annealing algorithm is used to blanking rectangular parts.)
