图像加乘性噪声后 有门限平滑 不加门限平滑后图像(image processing noise gate)

三谱混合相位子波估计！！ 这是我的一篇文章所涉及到的matlab 源代码，对搞物探的人很有帮助！hosa, hos_2, S4M是程序中用到的工具箱!(three mixed-phase spectra wave estimated! ! This is my one article, which was involved in the Matlab source code, engaged in geophysical helpful to the people! Hosa, hos_2, 4 months/S4M procedure is to use the Toolbox!)

进行功率谱估计的许多方法的matlab程序，可以运行的(Many power spectrum estimation method matlab program, you can run)

说明：  数据经过多进制QAM调制下，通过高斯信道的误码率比较(the rand data are modulated by MQAM ，then pass the gausschannel ，get the compared result of ber.)

这是<matlab程序设计教程>的书籍源代码。(this is the book code of matlab program design course)

是学习PCA特征提取的很好的学习资料，本程序的性能已经超过其他算法，线性调频脉冲压缩的Matlab程序。( Is a good learning materials to learn PCA feature extraction, This program has exceeded the performance of other algorithms, LFM pulse compression of the Matlab program.)

偏最小二乘法计算程序软件，实现最小二乘计算，包含各种最小二乘算法(Partial least squares computer program software, to achieve least squares calculation, includes a variety of least squares)

自己学习svm，编写的几个svm实例代码(Their own learning svm, svm example code written in several)

极端学习机分类、预测matlab函数，亲测可用，里面还有测试数据(ELM classification and regression source code, enabling prediction function)

说明：  几个模式识别的作业程序，自己写的。望指教哦，内容有感知器算法、多类感知器算法以及K均值算法(Several pattern recognition procedures, wrote it myself. Advice Oh look, the contents of perceptron algorithm, multi-sensor algorithm, as well as K-means algorithm)
