利用此函数可以在最小二乘意义上解决非线性曲线拟合（数据 拟合）问题。也就是说，给定输入数据xdata，以及观测的输出数据ydata，找到系数x，使 得函数F(x，xdata)能够最好的拟合向量值-MLS method not only can be applied for the purpose of curve (or surface) fitting, but also curve (or surface) interpolation when compactly supp

汽车滚动阻力系数f值的大小，标志着汽车行驶中滚动阻力的大小。基于试车道路滑行试验数据，采用滑行试验法计算汽车的滚动阻力系数。分析过程通过matlab编程实现。(the size of Car rolling resistance coefficient f value marks the size of the car driving rolling resistance. Based on the test data of the car road gliding, the rolling r
