首先,你提供数据有误.x数据 ≠ y数据（x数据35个、y数据33个）,这不符合拟合条件.
cftool 是Matlab曲线拟合工具箱.操作步骤如下：
1、在命令窗口中,输入x、y一系列相对应的数据,打开cftool工具箱；
>>x=[.],y=[.]
>>cftool
2、点击Data...,选择 X Data,Y Data,建立数据集(Create data set),然后关闭数据对话框(Cose)
3、点击Fitting...,点击新的拟合项目(New fit),选择拟合类型（Type of name）中的用户自定义函数类型（Custom Equations）,点击New,输入y=a/(1+(a/37000-1)*exp(-b*x)),选择OK,选择center and scale X data,选择Immediate apply,最后应用（Apply）
4、此时,就得到结果
如还有不明白,可以再提问.或请把正确的数据传上来,再求其拟合曲线.
