PCM编码实例。包括均匀量化编码，非均匀量化编码，及A率PCM编码。(PCM coding examples. Including uniform quantization coding, non-uniform quantization coding, and A PCM coding rate.)

图像处理Matlab源代码，包括二维离散余弦变换的图像压缩，采用灰度变换的方法增强图像的对比度，直方图均匀化，模拟图像受高斯白噪声和椒盐噪声的影响。 (Including discrete cosine transform image compression, the use of gray-scale transformation method to enhance image contrast, histogram equalization, analog image by Gauss white noise and salt and pepper noise.)

introduction to basic image processing using matkab and basic comments

grey forecasting,using poor information system(grey forecasting, using poor information system)

说明：  这是一个用带亮度傅立叶描述子提取纹理特征的程序(This is a band brightness using Fourier descriptors of texture feature extraction procedures)

对图像进行约束最小二乘滤波复原，并调用edgetaper函数,减弱噪声放大效应和振铃现象(image restoration deconvreg)

说明：  用matlab编辑平行因子分析法，程序不大，容易理解(Using matlab to edit parallel factor analysis method, the program is not big and easy to understand.)

说明：  浮点数的定义及计算方法，可用于初级学习之用(floap contral)
