FFT的matlab实现,利用蝶形算法计算fft的matlab(Matlab implementation of FFT, using the matlab fft butterfly algorithm)

DTMF报告和代码，基于simulink仿真，通过GUI调用m代码和simulink，可加噪音。(DTMF reports and code, based on simulink simulation, call m code and simulink through GUI, can add noise.)

特征选择方法，用于降低数据维数，常见的一种特征筛选手段，可以从大量变量中筛选特征变量实现保留变量与目标之间的最大相关性(feature selection method for mRMR)

说明：  基于模型参考自适应的异步电机转速辨识仿真模型(Based on Model Reference Adaptive Speed Identification of Induction Motor Simulation Model)

线性SVM分类，数据已给出，代码很详尽哈(Linear SVM classification, data has been given, the code is very detailed and Kazakhstan)

说明：  一本matlab初学者的入门级经典书籍编程人员案头必备的一本参考书籍,英文版,有助于提高英文及编程技术.(An entry-level matlab beginner programmers classic books necessary for a desk reference book, in English, help to improve English and programming.)
