Matlab-Num-Instante

规划问题，其中包含了规划问题的基本Matlab源程序，还有PPT的相关解释(Planning, which includes the planning of basic Matlab source code, as well as the relevant interpretation of PPT)

加窗傅里叶变换（windowed fourier transform_guassian）取hanning窗。(Windowed Fourier transform (windowed fourier transform_guassian) take hanning window.)

This is matlab code for SVD based image watermarking

主要用MATLAB对图像惊进行处理，对图像进行滤波器处理 给出滤波前后的图形很有实用(Main MATLAB to image surprised processing, the image filter processing are before and after the graphics are filter practical)

完整的ldpc编码程序，实现数字载体的ldpc编码译码以及信道传输仿真,利用生成矩阵和校验矩阵实现，含有自动生成随机错误以检测纠错能力功能(Ldpc complete coding procedures, digital carrier ldpc codec and channel transmission simulation using the generator matrix and parity check matrix realization, containing automatic generation of random error correction ability to detect functional)

This is upper successful cancellation for mobile communication

图像的平面微分平方和能够反映图像高频分 量的能量。用计算平面微分平方和的方法在空间域上计算相邻像素亮度差值的平方和，对应于在频率域上计算图像高频分量的能量和，此值越大，图像对焦越准确(Differential square image plane and the image can reflect the energy of high frequency. Computational method of Planar Differential squares calculated in the space domain to the square of the difference between the brightness of adjacent pixels and corresponds to the image in the frequency domain calculation of high frequency energy and, this value is larger, the more accurate the image focus)

matlab工具书/学习资料。详细收录并讲解了matlab的图像命令。(matlab books/learning materials. Matlab included and explained in detail the image command.)

说明：  elm算法，我做风电功率预测时用到过，比较好用。(Elm algorithm, I do wind power prediction used, relatively easy to use.)
