Dear all
as the title, why some of the built-in function of my matlab (2018b) can not work? like fit, confint...
x1=[178 1316 3236 5155 7075 8996 10916 12836 14756 16676 18568]'
y1=[1.0000 1.1848 1.4038 1.6632 1.9705 2.3347 2.7661 3.2773 3.8829 4.6005 5.4507]'
fitn=fit(x1,y1,'exp1')
>> fitn=fit(x1,y1,'exp1')
>>fitn =
[]
Thanks

The fit function used that way is part of Curve Fitting Toolbox, as is the confint function. You most likely do not have this toolbox installed. Check if it is installed using the ver function.
