基于扩展记忆的粒子群优化算法（Particle Swarm Optimization based on memory）(This paper combines SVM with improved PSO (Particle Swarm Optimization with Extended Memory, PSOEM) and then builds PSOEM-SVM forecasting model. The PSOEM searches the solution space intelligently and finds out the best one. Parameters in SVM are optimized by PSOEM, which implements automation of the parameter optimization avoiding the blindness of selecting parameters. Not only does it utilize the generalization feature of SVM, but enhance the global search ability of PSO (Particle Swarm Optimization). Thus, both accuracy and speed are increased at the same time.)

解决了三维数据可视化的问题；在三维网格点上数据绘制显示它的大小。 通过z轴坐标点更容易区分边缘颜色变化。可以通过设置线宽参数该选项设置为0。(This function solves the problem of visualization of 3 dimensional data in one plot(plot3). Data is plotted on a 3 dimensional mesh with point size showing value of it. Edge color changes via z axis to distinguish coordinate of points easier. That option can be turned off by setting the linewidth parameter to 0. )
