dataanalysis

信号与系统时频分析及Matlab的应用，设计z变换、fft变换、拉普拉斯变换等(Time-frequency signal and system analysis and Matlab applications, design of the z-transform, fft transform, Laplace transform)

在matlab软件平台上对一些需要调用的特殊函数的计算。(Special function calculation)

简易四则运算计算器，使用时需将.m和.fig文件放到matlab工作目录下（本人使用的是R2013，放到bin文件夹即可，其他版本放到对应文件夹，有的是work文件夹），然后在命令窗口输入.m文件的文件名，即可显示一个简易计算器界面。有0-9九个数字供点击输入数，有重置和正负号按钮，界面简洁，功能耐用(Simple arithmetic calculator should be used with the. M and. Fig file into matlab working directory (I use the R2013, into the bin folder to the other versions into the corresponding folder, some work folder) , and then in the command window. filenames m file to display a simple calculator interface. 0-9 nine figures for the number of click enter, and the sign has reset button, the interface is simple, functional and durable)

最小二乘优化算法。Matlab源码，直接可以使用。(Least Squares optimal affine subspace The zip includes: (1) lsqAffineSpace: a low level routine that takes a set of m-dimensional real sample data and returns the optimal-fit k-dimensional affine subspace, with some options for discarding outliers. (2) lsqPlane and lsqLine: lsqAffineSpace wrappers, that compute optimal line and hyperplane (plane, if the samples are 3-vectors) of the input samples. (3) lsqAffineTestScript: demonstrating usage of the functions.)

对一段语音进行加窗处理，在matlab下查看经过加窗处理后的语音信号。(For a voice to add Windows processing, on matlab check after add window under process after the speech signal)

this is matlab code for pprobality theory which is implemetatde in matab 7,6

matlab写的多目标进化算法，值得学习和借鉴，直接修改使用(The multi-objective evolutionary algorithm written by Matlab is worth learning and using for reference.)

优化的IIR滤波器，8个零点，8个极 点(optimization IIR filter, 8 0.1, 8 pole)

k-近邻算法 m文件 及其excel示范(this package invulved a m-file example of k-nearest neighbour and its corresponding excel file)

matlab simulink主要介绍了simulink模块的使用，适合初学者学习！(matlab simulink simulink module introduces the use of, suitable for beginners to learn!)
