说明：  粗糙集属性约简，包括正域的计算，约简结果的提取(Rough Set Attribute Reduction, including the calculation of positive fields, the extraction of reduction results)

说明：  自编多尺度样本熵程序，实例中用于一段轴承故障数据，简单易懂。MultiscaleSampleEntropy函数中的SampleEntropy也可以单独拎出来计算单个样本熵。(Multi scale sample entropy is used for a section of bearing fault data, which is easy to understand. SampleEntropy in the MultiscaleSampleEntropy function can also be picked up separately to calculate the entropy of a single sample.)

扩频通信系统仿真 ——系统将基带信号（即信息）的频谱扩展至很宽的频带上，然后再进行传输，即将欲传输的信息数据用伪随机序列编码调制，实现频谱扩展，然后通过信道编码发送出去；接收端采用与发送端完全相同的伪随机序列作为本地解扩信号进行相关处理，以恢复信息，最后进行解调，完成整个系统的接收。(Simulation of spread spectrum communication system- the system baseband signal (ie, information) be extended to a wide spectrum of frequency bands, and then transferred, will want to use transmitted information data sequence of pseudo-random code modulation, to achieve expansion of the spectrum, and then sent channel coding receiver and transmitter use the same pseudo-random sequence as related to the local despreading signal processing, in order to restore the information, the final demodulation, the receiver to complete the system.)

一个chirp信号，用来描述连续震动的正弦函数。(A chirp signal, which is used to describe the sine function of continuous vibration.)

滤波器，可以实现自相关功能，获取信号的信息。(Filter, you can achieve the autocorrelation function to obtain information signal.)

WAITINPUT Prompt for user input, but no longer than t seconds

multipath_chann.m 多径信道仿真(multipath_chann.m multipath_chann.m)

multivariate analysis tool

MOPSO代码实现，对MOPSO的算法进行了具体的代码描述，清晰地体现代码实现过程。(MOPSO code for MOPSO algorithms specific code description clearly reflect the code implementation process.)

主要是些matlab的常用指令，对大家可能会有所帮助(Mainly those commonly used matlab instructions may help to everyone)
