it is a matlab code for cyclic search in non linear programming.

Abstract— We propose a simple speech compression algorithm using subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm. Although speech data are stored in a semiconductor memory device, its capacity and the available network capacity are limited. Therefore, it is necessary to compress the data as much as possible. The first is that the reconstructed datum must be understood correctly. Speech signal is compressed with a ratio of 1/4 using the proposed subband division and ADPCM (Adaptive Differential Pulse Code Modulation) algorithm.

主要是用matlab实现的数字水印，其中用到的技术是lsb(Achieved using matlab digital watermarking, which uses the technology is LSB)

将输入d进行扩张，方法是在d的每个数据中插入M-1个零值。 如输入d=[1,2,3,4] M=3 输出out=[1 0 0 2 0 0 3 0 0 4 0 0](To expand the input d, the method is to insert each data d, M-1 zero value. If the input d = [1,2,3,4] M = 3 output out = [1 0 0 2 0 0 3 0 0 4 0 0])
