可以进行平面拟合，基于matlab语言-拟合

产生 50 个标准正态分布的随机数, 经验累计分布函数图.(Random number generated 50 standard normal distribution, noting their distribution characteristics, and to draw experience cumulative distribution function diagram.)

迭代的动力缩聚法计算结构的前两阶频率和阵型（4个自由度）(Iterative dynamic condensation method to calculate the structure of the first two natural frequencies and formation (4 degrees of freedom))

说明：  1跨35米的车桥耦合程序。Fortran编写(1, 35 meters span bridge coupling procedures. Fortran write)

说明：  复合材料层内基于断裂韧性退化的VUMAT子程序(VUMAT subroutine based on fracture toughness degradation in composite laminates)

速度曲线规划，在给定长度path 曲线上，根据各waypoint的速度约束，规划出平滑的速度曲线(speed curve planning.In a given length path curve, according to the speed of the waypoint constraints, planning a smooth speed curve.)

Cavity Matlab SIMPLE algorithm

说明：  多维随机数的生成方法，一维随机数生成方法，高维随机数的生成方法(Generation methods of multidimensional random number, one-dimensional random number and high-dimensional random number)

利用matlab实现的部分CFD功能的代码，很有参考价值(Matlab to achieve part of the CFD function of the code, a very valuable reference)

和大家分享一个全相位FFT，matlab程序，程序中全相位fft实现方法有两种，注释掉的根据原理推到得来，自己看吧。(And share a full-phase FFT, matlab program, the program fft implementation in all phase two, comment out the basis of the principle pushed to come, see for yourself.)

说明：  FFT，整型数据代替浮点型数据 本程序是搜集资料并加上自己的分析，整了很长时间才测试通过的FFT程序，运行时间和所占内存方面都比较满意。(FFT, integer data instead of floating point data This program is to collect data and add their own analysis, the FFT program passed the test for a long time, the running time and memory occupied are relatively satisfactory.)
