matlab用lsqcurvefit拟合数据 为什么会停止?应该咋解决?Local minimum possible.lsqcurvefit stopped because the final change in the sum of squares relative to its initial value is less than the default value of the function tolerance.

Local minimum possible.
lsqcurvefit stopped because the final change in the sum of squares relative to
its initial value is less than the default value of the function tolerance.

用二维插值,如果插值为网格节点用命令interp2,如股票插值节点为散乱节点用griddata,老师开始的资料有介绍具体的功能,而回归分析的话可以用到多元线性回归,一个因变量,多个自变量,或者用到多项式回归也是可以的,（没有清楚看你的题目）,而拟合的话,用到曲线拟合用matlab中的优化工具箱中lsqcurvefit函数,具体我没用过,按原理的话是可以达到要求的.
