用于文本分析和分类的pLSA(Probability Latent Semantic Analysis)的Matlab算法，含有测试数据及算法原理介绍。也可用于图像分析。相比原来的版本，增加了示例程序demo.m，以实现可视化效果，用户更容易使用和理解pLSA算法。(For text analysis and classification of pLSA (Probability Latent Semantic Analysis) of the Matlab algorithm with test data and algorithm theory description. Can also be used for image analysis. Compared to the original version, an increase of sample programs demo.m, to achieve the visual effect, the user can more easily use and understand the algorithm.)

Consider generating 64 samples of a sinusoidal signal of frequency 1KHz, with a sampling frequency of 8KHz.

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解， ％ 以说明信号和噪声在各个尺度上的表现。(this program as a "Blocks" signal, then add white Gaussian noise, reuse db3 wavelet decomposition,% to illustrate signal and noise in various scales performance.)

继续上传基于稳态kalman滤波器事例讲解，这里可以不需要考虑观测系统中的噪声。(to upload based on steady-state Kalman filter on the case, it need not consider here Observing System of noise.)

主成分分析MATLAB相关程序主成分分析MATLAB相关程序(Principal component analysis related MATLAB program )

对于matlab初学者很好的基本的经典的源代码学习例程(Good for beginners basic matlab classic study of the source code routines)

直角坐标转换到极坐标下代码，以图像中心为原点，水平向右为0°方向，顺时针旋转生成极坐标图像。(converts a given image from cartesian coordinates to polar coordinates.)

对水印图像进行置乱，然后嵌入到载体图像小波域中的细节子带中(the watermark image is Scrambled, and then embedded into the details of wavelet sub-band domain)
