Get the curve parameters in the fit function

How to get the p1 and p2 values after using the fit function. i.e.

[curvepar, fitpar]=fit(rand(100,1), rand(100,1),'poly1')
curvepar = 

       Linear model Poly1:
       curvepar(x) = p1*x + p2
       Coefficients (with 95% confidence bounds):
         p1 =    -0.06171  (-0.2875, 0.1641)
         p2 =      0.5492  (0.421, 0.6774)

fitpar = 

             sse: 9.0309
         rsquare: 0.0030
             dfe: 98
      adjrsquare: -0.0072
            rmse: 0.3036

I want the numerical value for p1 and p2? i.e

a=p1; b=p2;
 disp(a)

Hi Denise,

follow that command with

p=coeffvalues(curvepar)

The more 'convenient' they make some of these functions, the harder it is to pry information out of them.

Hello dear David Goodmanson,

thank you for your helpful answer, I appreciate your help.

I want to extend your answer to be more precise for dear Denise,

here it is:

p = coeffvalues(curvepar);
a = p(1);   % which displays the value of p1
b = p(2);   % which displays the value of p2
