二次采样以确定像素间的相关性，然后对两个采样结果同时嵌入水印，利用的是倒谱变换(second sampling to determine the correlation between pixels, then the two sampling results also embedded watermark, make use of Cepstrum)

一维定长热传导方程，时间项采用向后差分，隐式求解。(One dimensional heat conduction equation of time length, using backward difference, implicit solution. )

motion estimation it estimates the motion vectors of hexagon search algorithm and estimates its direction

cost231信道模型，做通信仿真都知道还是很有用的(cost231 channel model, simulation of communication to do all know that it is useful for)

说明：  这是一部关于介绍MATLAB主要函数与公式命名的书籍(This is a major function on the formula introduced named MATLAB books)

boost model for dc to dc conversion

说明：  RS码(Reed—Solomon码)是多进制BCH码，也是目前最有效、应用最广泛的差错控制编码。它具有很强的纠错能力，随机错误、突发错误都能纠正，特别是在短的和中等码长其性能接近于理论值。再加上构造方便，编码简单，设备不复杂，因此在实时性要求较高的数字通信及深空通信方面有广泛应用(RS code ( Reed- Solomon code ) is a multiple of BCH code, is currently the most effective, the most widely used error control coding. It has a strong error correction ability, random error, burst error can be corrected, especially on short and medium length code performance close to the theoretical value. Plus convenient construction, simple coding, equipment is not complex, so the real-time digital communication and deep space communication is widely used )
