各种数值计算的基本算法：求解代数方程、微分方程组、各种多项式插值等，matlab语言开发，适用于工科学生(A variety of numerical calculation of the basic algorithm: solving algebraic equations, differential equations, a variety of polynomial interpolation, matlab language development for engineering students)

直流斩波电路的mtalab仿真实例，可以观察波形，便于延伸各种仿真，继续仿真(DC chopper circuit mtalab simulation example, the waveform can be observed, to facilitate extension of the simulation, the simulation continues)

The code implements the following paper: Guorong Xuan, Jiang Zhu, Jidong Chen, Shi Y.Q., Zhicheng Ni, Wei Su, "Distortionless data hiding based on integer wavelet transform" IET Electronics Letters, Volume: 38, Issue 25, page 1646- 1648, December 2002. (ISSN: 0013-5194) The watermark embedding and extraction modules have been implemented separately. The watermark embedding module embeds the watermark using bitplane compression in the integer wavelet transform domain. The watermark extraction module extracts the previously embedded watermark and restores the original image. A logo image is used as a watermark but can be replaced with any thing.
