hey, guys,

I have two sets of data, like

x1.beta = [0.4233 0.2941 0.2163 0.1649 0.1298 0.1051 0.0864 0.0727 0.0618];
x1.A = [0.0492 0.0553 0.0566 0.0567 0.0529 0.0535 0.0495 0.0446 0.0421];

x2.beta = [0.3375 0.2323 0.1714 0.1296 0.1028 0.0831 0.0686 0.0572 0.0486];
x2.A = [0.0518 0.0566 0.0557 0.0544 0.0499 0.0507 0.0447 0.0402 0.0392];

plot([x1.beta;x2.beta],[x1.A;x2.A],'.')

A is a function of beta, and I have two sets of A and corresponding beta,
for one set of data, I know how to fit it.
But I want to fit these two sets data to one curve. how to do it? thanks a lot
