输入：为需要压缩图象的名称,该主程序仅能构处理256灰度图,读者可以自行改编为RGB处理；ratio为压缩比率；level为小波分解的级数 输出:是解压完毕的图象数据矩阵-input : the need for image compression name, the main program can only handle 256 gray level structure, Readers can own adaptation of RGB; ratio of compression ra

使用半适应的huffman算法实现了文件的压缩和解压-use semi-adaptation Huffman algorithm document compression and decompression

Where H represents the hermitian transpose. The complex vector of weight adjust the amplitude and phase. The desired beam can be produced by adding together the MMSE weight adaptation with the steepest decent algorithm produces LMS algorithm[7]. For
