Technical-indicators-by-Matlab
用matlab编写了20几个常见的技术指标，方便大家开发策略时候，直接调用。
1）编写这些函数不是技术活，完全是体力活
2）之所以编写这些函数，一来是自己研究所需，二来自己编写过程中能够感悟到蕴含在公式中的思想
3）几乎所有函数，我都用数据测试过，并和交易开拓者、同花顺等计算的值进行了比对，最大程度
上保证指标算法的准确性。虽然已近极力避免错误，但是还是可能出现一些这样那样的错误，所以
请批判性使用这些函数
4）如果对这些函数有疑问（比如有些指标可能会有不同的处理方法），请参见函数中的参考文献部分
5）如果您的策略用到了这些函数，请一定研究这些函数的编写过程，避免未来函数、偷价漏价对你造成的干扰。(20 using matlab few common technical indicators, to facilitate the development of strategies when called directly.
1) preparation of these functions are not technology live, is completely manual labor
2 thoughts) reason to write these functions, one is required for their own research, and secondly to be able to comprehend the process of writing their own inherent in the formula
3) Almost all of the functions that I have tested with the data, and the Trail Blazers and trading, such as flush with the calculated values were compared right, the greatest degree of
On indicators to ensure the accuracy of the algorithm. Although almost try to avoid mistakes, but still may be some kind or another error,
Please use these critical functions
4) If you have questions about these functions (for example, some indicators may have different processing methods), see the References section function
5) If your policy to use these functions, be sure to study the process of)

Reassigned-Cohen-Class
介绍了 Cohen类双线性时频分布并针对交叉干扰项影响无法完全消除的问题进行了重排时频变换以提取及分辨
含有白噪声和窄带周期干扰的局部放电信号。处理仿真和现场检测到的局部放电超声信号时根据白噪声和窄带
周期干扰信号在时域上的平稳性特性发现重排 Cohen类时频变换方法不仅可以很好地将局放信号和背景噪声以
及窄带周期干扰信号分辨开来,而且大大减弱并抑制了交叉干扰项的影响,保持了更高的时频分辨率和时频聚集
性,从而验证了重排 Cohen类时频变换方法的有效性。
(In order to express the partial discharge ( PD) information of gas insulated switchgear ( GIS) in time-frequency
domain, weintroduced theCohen? s class bilinear time-frequency distribution and its reassigned time-frequency
transform method to pick up and distinguish theultrasonic signals in field from the whitenoises and narrow band
periodic interference signals using the acousticemission ( AE) technology. After the processing of the simulated and
PD ultrasonic signals in field, and according to the stationary feature of white noises and narrow band interference
signals, wedraw a conclusion that the reassigned time-frequency distribution method can not only distinguish thePD
signal from back ground noises and narrow band interference signals, but also decrease and restrain the influenceof
cross-items, and acquire better time
