曲线拟合
- 曲线拟合:通过给定的一组二维坐标点,利用线性代数中矩阵求逆的知识,从这些数据中找出规律性,预测原函数f(x)的表达式,以消除所给数据的局部波动。一次拟合出来的函数图像是直线,二次拟合出来的图像是抛物线。两者相比,二次拟合逼近程度更高。(curve fitting through a given set of two-dimensional coordinates, using the inverse matrix in linear algebra knowledge, find out the
拟合曲线
- 鼠标点击任意两点,两点之间进行直线拟合,继续点击,增加点的数目,多点之间进行多次插值拟合(Mouse click any two points, between two points to a straight line fitting, continue to click, increase the number of points, multiple points between multiple interpolation fitting)
