做一个特征提取的模拟。功能良好。非常实用(To make a feature extraction simulation. Good function. Very useful)

公式法产生任意均值、方差和长度的高斯白噪声(Formula method produce any mean, variance and the length of the Gaussian white noise)

对正弦信号进行FFT变换 画频谱图，进行频谱分析，可以计算出信噪比(Sinusoidal signals of paintings transform FFT spectrum chart, spectrum analysis, signal to noise ratio can be calculated)

adaboost算法，采用十折分析法对参数进行优化，弱学习方法是BP神经网络(Ten fold methed on BP-adaboost)

BP神经网络用于分类与回归的matlab源码 注释很详细(1、NeuralNetwork_BP_Classification.m- 分类 2、NeuralNetwork_BP_Regression.m- 回归 )

说明：   该程序实现时域LMS算法，并用统计的方法仿真得出不同步长下的收敛曲线( Of the time domain LMS algorithm program implementation and use of statistical methods are not synchronized long simulation shows the convergence curve under)

Simpson rule Matlab code

小波变换 ，平稳小波变换，对信号进行8层分解，对第4层处理(Wavelet transform)

C语言与MATLAB接口编程实例，主要是一些C语言与MATLAB 接口的程序，希望对大家有用(C language MATLAB interface programming examples, some of the C language and MATLAB interface program, and hope to be useful)
