趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)

DC-DC升降压电路,主要实现升压和降压功能，采用PI电压电流双环控制(DC-DC buck-boost circuit, the main step-up and step-down function, using the PI voltage and current loop control)

本程序是以电力系统算例 IEEE33为具体例子 ，只计算初始网络的节点电压 仅供参考(This procedure is based on the power system example IEEE33 for specific examples, only the initial network node voltage for reference only)

here is fantastic iso clustering code which i test it frequently and find it satisfactory. it does k maen clustering in two dimensional data.
