Offhand, I don't know any way to change the display within the tool itself. With this said and done, its fairly easy to
1. Solve your problem using the sftool interface 2. Export your solution to base MATLAB 3. Display the resulting coefficients using the "long" format
Here's exactly what you're going to want to do
There is a menu inside sftool called "Fit" Open this up and chose the option called "Save to Workspace".
By default your model will be saved to the workspace as "fittedmodel". fittedmodel contains all of the regression coefficients generated by sftool.
What you want to do now is type "format long" to change the display in base MATLAB. You can then grab the individual regression coefficients from the fittedmodel. For example, your constant is stored as p0. You can retrieve the estimate for the constant by typing
fittedmodel.p0
