说明：  MATLAB结合autoCAD关于曲面绘图的案例，有参考价值。(MATLAB combines autoCAD drawing on the surface of the case, the reference value.)

说明：  本文件为Matlab环境下，不用小波工具箱编的小波变换源代码。(this document for Matlab environment, not wavelet Toolbox series of the wavelet transform source code.)

EasyEnsemble和BalanceCascade是两类不平衡数据集的学习方法(EasyEnsemble and BalanceCascade are two class-imbalance learning methods. They can adaptively exploit the majority class examples, avoiding important majority class examples to be ignored by common under-sampling while maintaining the fast training speed of under-sampling. )

MATLAB中各代码、函数间的参数传值验证代码，有助于理解matlab中的传值概念(MATLAB, the code, the function returns the value of the parameters between the validation code helps to understand the concept of traditional values ​ ​ in matlab)

粒子群优化算法（可以应用在寻优建模过程中）(Particle Swarm Optimization (can be applied in the modeling process optimization))

matlab编写的读取IGS广播星历文件（.n）文件的程序。读取完成后将数据分类储存为cell格式和struct格式。(Matlab prepared to read IGS broadcast ephemeris file (.N) file procedures. After reading is finished, the data is sorted into cell and struct format.)

该程序利用同态滤波的方法对心音信号求解包络(homomorphic_envelope)

这是关于a次方的FFT变换的matlab程序，很好用！！！希望与各位同享(This a power of the FFT transform Matlab procedures, easy to use! ! ! Hope to share with you!)

自己写的一个2DPCA的代码，可使用，可调节，有适当的地方可改动(2DPCA。。written by myself maybe useful for you,please to know it)
