灰度共生矩阵提取特征值，最近邻算法，进行纹理图像分类。creat_apprentissage用来训练样本，cooccurence是灰度共生矩阵提取特征值，knn是进行k最近邻算法，classif是纹理图像分类(coocurence matrix，using K nearest neighbor to classify textures images.)

很好的matlab学习资料，由浅到深的解析，附带源码(Matlab good learning materials, from shallow to deep analysis, with source code)

采用时频聚集性较好的线性调频信号作为线性时不变系统输入激励，采用Gabor字典作为过完备原子库。在利用传统系统辨识法之前先利用稀疏分解算法将输出信号进行去噪处理，显著提高系统辨识精度。 具体包括互谱算法，信号的Gabor稀疏分解的详细代码(Space can be a time for sparse decomposition to solve the problem of huge memory needed。This approach, combined with the rapid decomposition of FFT for signal ,so as to achieve satisfactory results.)

利用互模糊函数完成无源连续波雷达的相参积累(Using CAF to complete the coherent integration ofcontinuous wave passive radar )

matlab符号运算的ppt讲解教程，讲解通俗易懂，易于学习(ppt matlab symbolic computation tutorials explain, easy to understand explanation, easy to learn)

载波恢复算法的MATLAB实现，很具有参考价值，精度满足要求(practice algorithm for carrier frequency estimate)

说明：  基于Matlab／Simulink的异步电机直接转矩控制系统仿真(Based on Matlab/Simulink for Induction Motor Direct Torque Control System)

The code is a Matlab program which can be use to calculate the energy distribution of grating. The method used is RCWA method.

it is example4 of capture4 from widrow book. it is so good for learning many things.
