load flow study using gauss siedel method

given a line function, compute the intersection of the line with the perimeter of a 2D box so that the line can be plotted. called by perceptron.m.

核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。(Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand)

说明：  通过simulink仿真模拟不同光照强度下的光伏模块串后的光伏特性，可以进行局部阴影下的光伏发电MPPT模拟仿真，仿真结果为多峰值形式，符合文献中规律特点，结果可导入工作空间，利用MATLAB进行绘图。(Through Simulink simulation, the photovoltaic characteristics of photovoltaic modules in series under different light intensity can be simulated, and the MPPT simulation of photovoltaic power generation under local shadow can be carried out. The simulation results are in the form of multi peak, which conform to the characteristics of the literature. The results can be imported into the workspace and drawn by MATLAB.)
