属于matlab程序，利用相场法来求解任意脆性断裂问题的裂纹拓扑，具有高鲁棒性(It belongs to the matlab program and uses the phase field method to solve the crack topology of arbitrary brittle fracture problem. It has high robustness.)

LU分解的过程演示，本人原创，测试无误，内含详细注释。 (LU decomposition procedure demonstrates I originality, test correct, containing detailed notes.)

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编写的基于决策树的ID3算法实现，模式识别，人脸识别。压缩包中包含两个源文件和测试图片，ID3源文件为主代码，fi为求熵函数。(MATLAB prepared based on the ID3 decision tree algorithm, pattern recognition, face recognition. Compressed package contains two source files and test images, ID3-based source code files, fi for the sake of entropy.)

C++ version (OpenCV) of the Matlab built-in functions accumarray.m and gradient.m
