利用：plot，stem，grid，line，axis，xlabel，ylabel，title 等绘制阶跃函数的图像。(draw the map of step function.)

说明：  ofdm的变成实现，一本中文书上的例程，供大家参考(The realization of ofdm, a routine in a Chinese book, for your reference)

数学建模中某些算法的解法,关于数学模型第三版姜起源 谢金星等的作品。。。。。(some solutions about matlab.)

XFEMz准静态,部分编程计算的源代码，断裂力学方面的(XFEM QUASISTATIC VARIABLE)

C均值聚类源码，C均值聚类分类。根据课本教材内容。(C-means clustering source code, C means clustering. According to the textbook teaching materials.)

自己写的关于粒子群算法求函数最小值的例程，简单易懂，对理解算法有很大帮助(Wrote it myself on the Particle Swarm Optimization for the minimum function of the routine, easy-to-read, to understand the algorithm are very helpful)
