These are MATLAB codes for implementing Chebyshev-Type 1 Bandpass and Bandstop filters.

柱体 TE_TM 波散射 采用的方法为矩量法由于基函数和权函数选取的是相同的，故称为伽略金(Galerkin)法。

生成进制数为4，调制指数为1的4CPFSK信号(Generate a hexadecimal number is 4, the modulation index for 1 4CPFSK signal)

潮流程序。。好好利用，可以更改，可以通用(power flow )

采用hog+SVM对路标进行识别，先训练再测试，准确率达到百分之九十四左右。(Hog +SVM is adopted to identify road signs, which is trained first and then tested, with an accuracy rate of about 94 percent.)

LDA算法的matlab程序。本代码是对一维信号进行LDA降维处理的函数。(LDA algorithm matlab program. This code is a one-dimensional signal processing functions LDA dimensionality reduction.)

Sparse Recovery Experiments with Sparse Matrices

Imperialist Competitive Algorithm (ICA)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

matlab教材中经典的语音增强算法，voice enhancement 先读入语音文件，然后计算前后信噪比，最后画出波形。(The classic textbook matlab speech enhancement algorithms, voice enhancement before reading the speech file, and then calculate the signal to noise ratio before and after the final draw waveforms. )
