In matlab can do MPPZ with notchblook and indefeed hyporeness.

我所见过的最实用的matlab编程实用教程，内容涉及到数据处理的方方面面，还有生成各种图表的方法，都有例程(I' ve seen the most useful and practical tutorial matlab programming, content related to all aspects of data processing, as well as the method generates a variety of charts, there is routine)

计算两个信号的功率谱密度，通过两个信号的谱相关系数决定频点是否参与叠加计算，以控制功率谱密度质量。(Calculation of the two signal power spectral density, spectral signals through two related factors involved in the decision whether or not frequency superposition calculation, in order to control the quality of the power spectral density.)

SPWM with matlab/simulink

说明：  自适应滤波器的matlab源代码，非常好用，可以实验下(Adaptive filter matlab source code, very easy to use, you can experiment under)

说明：  这是一部matlab的教材，比较基础，适合初学者，不知道有没有人上传，先发一下，如果有劳请版主删掉！(It is a matlab materials, basis of comparison, for beginners, do not know if anyone upload, start that, if there are moderators, please delete labor!)

说明：  根据风速公式在SIMULINK环境中搭建的渐近风速的模型，可运行。(According to the formula， in the SIMULINK environment wind asymptotic velocity of the model is builded,and it can run)
