Hey guys,
When I wrote a custom equation, then matlab solves the equation depending on my graph and give me results. However, result followed by a boundaries in paranthesis like that. What is the meaning of (-10.62, 1.34)??? Thank you

Those are approximate confidence limits on the variable as estimated. (Not always very good limits, as I said, approximate.)
If they are wide, then view it as if the solver is not very confidant in the result. They may be wide because you have crappy data. It may be because your model is poor. It may indicate insufficient data. If they are norrow limits, then it suggests you have done a decent job of estimating the parameter.

The most significant problem with your ‘e’ parameter is that the confidence limits include 0. That means ‘e’ is not significantly different from 0, and is therefore not needed in the regression model.
