一组空间离散点数据，利用最小二乘法拟合出一平面,point surface

采用最小二乘的方法拟合出了一条空间直线，用VC6.0编写的控制台程序-Using the method of least squares fitting of a straight line in space with console procedures prepared by VC6.0

拟合圆程序，实现根据测量点实现二维平面内圆的拟合，可以输入测量点，C语言实现-Circle fitting procedure, to achieve the realization of measurement points in accordance with two-dimensional plane of fitting a round, you can enter the measurement points, C language
