One option is to use sprintf() to make a string, e.g.:

legend(sprintf('alpha1 = %g, alpha2 = %g', alpha1, alpha2));

And so on. The formatting of inputs to sprintf() is the same as for fprintf() - or "help sprintf" will of course tell you what you need.

I don't fully understand how you want the values to be included, but you'll probably want to use the sprintf command:

alpha1 = 0.1;
beta1  = 0.2;

figure
h = plot(rand(7,2));
legend(h,sprintf("alpha1 = %7.2f",alpha1),sprintf("beta1 = %7.2f",beta1))
