adding constaints to fmincon code

hello,i have wrote the following code for optimization.

how do i add the following constraints that my fmincon will run so that

0.5<p(1)<1

0.7<p(2)<0.8

0.5<p(3)<0.9

Thanks

p0 = [1,1,1];   
yp = @(p) p(1) + p(2)./xm + p(3).*log(xm);  

objective = @(p) sum(((yp(p)-ym)./ym).^2);
popt = fmincon(objective,p0);

plot(xm,yp(p0),'bx')
hold on
plot(xm,ym,'ro')
plot(xm,yp(popt),'gs')

See the description of the lb and ub input arguments and the "Minimize with Bound Constraints" example on the documentation page for fmincon
