说明：  利用粒子群优化算法对支持向量机中的核函数参数和惩罚参数进行优化是非常有效的手段，可以大大提高鲁棒性。实际过程中读者可通过下载我上传的代码，简单进行修改和阅读附件论文即可快速掌握相关方面的知识，快速使用这一方法。(Particle swarm optimization (PSO) is a very effective method to optimize the kernel function parameters and penalty parameters of SVM, which can greatly improve the robustness. In the actual process, readers can quickly grasp relevant knowledge and use this method by downloading the code I uploaded, simply modifying and reading the attached paper.)

IMPMET Standard impedance matrix (metal surface) Returns the complex impedance matrix [EdgesTotal x EdgesTotal] Uses 9 integration points for every triangle (barycentric subdivision) The impedance matrix is calculated as a sum of the contributions due to separate triangles (similar to the "face-pair" method).

这个描述的频率细化技术，想使用这样的方法，对密集的地方进行放大。(Detailed description of the frequency of this technology, you want to use this method, place of intensive amplification.)
