级联电压型逆变器H桥五电平，目前工业应用较多的一种逆变方式(Cascaded voltage inverter H-bridge five level, industrial applications currently more of a way of inverter)

说明：  matlab中的Rayleigh信道模型，基于基于Clarke模型的Jakes仿真器(Rayleigh channel model in MATLAB, Jakes simulator based on Clarke model)

说明：  混沌时序多步预测函数 chen函数的matlab仿真，非常有用，连续的非线性函数(Multi-step prediction of chaotic time series function chen function matlab simulation, very useful, continuous nonlinear function)

针对天线阵列，偶极子等天线模式的仿真程序，可以调节波长，倾角等参数，并能画出二维和三维的图像，希望能够对大家有所帮助(For antenna array, such as dipole antenna pattern simulation program, you can adjust the wavelength, inclination and other parameters, and can draw two-dimensional and three-dimensional images)

这是2003年全国大学生数学建模竞赛A题MATLAB源代码(This is the 2003 National Mathematical Contest in Modeling A title MATLAB source code)

PPCA变换的MATLAB程序代码 需要的可以下载 (PPCA transform MATLAB program code needed to download)

本算法结合小波变换和SVD奇异值变换，实现了水印的嵌入和提取，载体图像的鲁棒性和水印的不可见性，提取出的水印图像的和原水印图像基本一致，抗攻击性强。(The algorithm combines wavelet transform and SVD singular value transformation, achieved watermark embedding and extraction, vector image watermark robustness and invisibility, the extracted watermark image and the original watermark image are basically the same, anti-attack and strong.)

说明：  较为详细的陈述了MATLAB用于图形图像处理的源程序(A more detailed statement of the MATLAB image processing for graphics source)
