基于MATLAB的小波变换信号消噪处理.rar这是一片期刊，主要讲述了小波变换在信号消噪方面的应用，相信对做这一方面研究的朋友会有帮助(MATLAB-based signal denoising wavelet transform treatment. Rar This is a journal, focuses on the wavelet transform in signal denoising applications, I believe that to do this aspect of the study will be helpful to Friend)

libsvm工具箱，用于分类的绝佳工具，也可用于非线性回归及预测，或拟合，其中文本分类是其长项，回归性能非常好(libsvm toolbox, an excellent tool for the classification can also be used for non-linear regression and forecasting, or fitting, of which text categorization is its long entry and return to a very good performance,)

说明：  This is very simple matlab code for laplacian pyramid used in contourlet transform.
