reading elements of cfit

I want to assign the various values returned from fit (cf_) to variables. How do I access the 95% confidence bounds?
e.g.
[cf_, G] = fit(X,Y, etc.);
A = cf_.a; B = cf_.b; etc.
but ? = cf_.a confidence bound.
thanks

Easy enough. Consider the simple model:
x = rand(10,1);
y = rand(10,1);
mdl = fit(x,y,'poly1')
confint(mdl)
So as you see, confint produces confidence intervals on the parameters.
If you wanted confidence intervals on a predicted point, here, at x == 0.25...
predint(mdl,0.25)
