matlab环境下编成的用于回归的支持向量机源程序(svm for regression)

改程序很好的描述了分布式电源出力的限制与优化，迭代次数较少 (Reform program is well described by a distributed power supply constraints and optimization, fewer iteration times )

利用MATLAB实现图像的离离散余弦变换的源代码可直接使用。 (The source code using MATLAB' s image away from the discrete cosine transform can be used directly.)

计算信号相关性的传统方法，利用卷积来计算。(The traditional calculation of signal correlation methods, the use of convolution calculation.)

A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system.(A new method for periodic scattering problems using 2nd kind boundary integral equations and the free-space Green s function, adding extra degrees of freedom on the unit cell walls, and imposing quasi-periodicity in an expanded linear system. This avoids the problems with the standard approach, namely: the quasi-periodic Green s function is slow to evaluate, it diverges at Wood s anomalies, and it does not handle large aspect ratios well. Our new approach cures all three issues, and can easily be `wrapped around an existing code (e.g. fast-multipole acceleration) for the isolated-obstacle scattering problem. It includes the latest talk slides: "A new integral representation for quasi-periodic scattering problems in two dimensions")
