matlab dsp中函数downsample和upsamplec代码(matlab dsp functions in downsample and upsamplec code)

采用国际标准测试图lena进行测试。分别采用“基于等间隔采样的图像缩小”、“基于局部均值的图像缩小”两种方法进行图像缩小。并附有注释、程序清晰、易于阅读。相信图像初学者阅读后必定会有很大的收益。(jiyudengjiangecaiyangdetuxiangsuoxiao, jiyujubujunzhidetuxiangsuoxiao,)

简单的sparse coding的小程序，基本可以了解sparse coding的工作过程。(Simple sparse coding small procedures, the basic can understand the working process of sparse coding.)

说明：  所传为共轭梯度法和线性加权法，这两种方法在优化中有较大的作用！(The transfer to the conjugate gradient method and linear weighted method, the two methods in optimization have a greater role!)
