Converting the outpur of a fit (e.g. sfit) into a string format, then pasting the text to a Text Area in app desginer

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)"

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.

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!
