Obtaining standard deviation in cftool

I have [x,y] as my data and I want to fit a linear line to it. My question is can I obtain standard deviation for the linear line that my data is fitted to?

Thanks

The thing labeled RMSE is the root mean squared error. It's an estimate of the standard deviation of the residuals or error term. Maybe that's what you want.

If you want a different notion of standard deviation, please explain further.
