说明：  一段带噪信号经过一butterworth低通滤波器后的输出，再求出其频谱！(butterworth)

BP神经网络代码，使用LM算法（高斯牛顿法的改进，具有很好的鲁棒性）(BP neural network code, use the LM algorithm (modified Gauss-Newton method has good robustness))

DDS(快速正交调制）生成正弦波形，利用相位累加字进行累加，查找查找表内容输出正弦数据，在通信领域应用很多，我采用的是matlab的simulink进行前期仿真(DDS (fast quadrature modulation) to generate sine wave, the use of the word to accumulate phase accumulation, content output sine lookup table lookup data in many applications in the communications field, I used to pre simulink of matlab simulation)

基于k近邻规则的PCA方法，改进的主元分析法用于故障诊断(PCA based on KNN)

说明：  面包师图像置乱算法,可以图像进行置乱处理。(a method which can resort image)

说明：  Matlab中的fft分析含噪声的信号，其中有直接FFT，时域同步平均后FFT，频域同步平均后FFT(Matlab s fft analysis with noise signals, which have a direct FFT, time-domain synchronous average, after the FFT, frequency domain synchronization for after averaging FFT)

It is mainly used for fingerprint recognition in matlab

This program can be used for plotting wavelet function.

A system for disciplined convex programming
