说明：  计算数组平均值，以求平均电流，进行异步电机驱动系统逆变器故障检测(Calculate the average value of the array to get the average current and detect the fault of the inverters in the asynchronous motor drive system)

UR旋转矢量转化，转化为RPY坐标，更加适合编程，非常靠谱(UR Rotation Vector Conversion)

多元一次方程在求解时，会出现解不容易求出的现象，那么利用矩阵的变换，直接输入相关多元未知数的系数，然后利用高斯消元法，进行多次迭代后，可以求出各个未知变量的值，同时，也可以很清楚的显示运算过程的中间步骤和中间的高斯消元的基本原理
