用origin8.5進(jìn)行非線性擬合時跳出一個對話框,內(nèi)容如下:Fit did not converge - mutual dependency exists between parameters. You may have overparameterized the fitting function. Fixing one of them may eliminate this problem. Fitting was done with weights. Check weighting method and error bar values for possible inconsistencies, or try fitting again with weights turned off. 這是神馬意思,說我擬合的不好嗎,可看著圖還不錯啊,求大神指點 |
