I have two problems:
1- I don't know how I can convert the output of a fit, which in my case comes as the class "sfit", into a text format that can then be edited further. Example of the fit:
Linear model Poly11:
CTEta0Fit(x,y) = p00 + p10*x + p01*y
Coefficients (with 95% confidence bounds):
p00 = -1.718 (-1.945, -1.492)
p10 = 18.85 (17.33, 20.38)
p01 = -0.006215 (-0.007869, -0.00456)
2- When I do this, is there a possibility to copy this text into a Text Area in the App Designer? I would like to create something like Log interface where a summary of activities is shown.

Another option (which does essentially the same thing) is this:
load census;
f = fit(cdate,pop,'poly2');
s = formattedDisplayText(f)
s =
" Linear model Poly2: ary(x) = p1*x^2 + p2*x + p3 Coefficients (with 95% confidence bounds): p1 = 0.006541 (0.006124, 0.006958) p2 = -23.51 (-25.09, -21.93) p3 = 2.113e+04 (1.964e+04, 2.262e+04)"

For example,
load census;
f=fit(cdate,pop,'poly2');
s=string(evalc('disp(f)'))
s =
" Linear model Poly2: f(x) = p1*x^2 + p2*x + p3 Coefficients (with 95% confidence bounds): p1 = 0.006541 (0.006124, 0.006958) p2 = -23.51 (-25.09, -21.93) p3 = 2.113e+04 (1.964e+04, 2.262e+04) "
is there a possibility to copy this text into a Text Area in the App Designer?
Of course!
