多点最小二乘法平面方程拟合计算，附有详细说明和源代码-Multi-point calculation method of least squares fitting plane equation

可以进行空间曲面的拟合 用于曲面拟合的代码：圆 球 直线 平面拟合都有-Surface fitting code: round ball linear plane fitting

采用的是脉冲对消法，BP神经网络用于函数拟合与模式识别，采用的是通用的平面波展开法。- It uses a pulse of consumer law, BP neural network function fitting and pattern recognition, Using common plane wave expansion method.
