I need a beta vs eps plot of the curve t^2-d. The expression of t and d depends on x, y where x, y depend on beta. Please help. Ranges of beta and eps are both equal to 0:.01:1,
alpha=1.5; A=0.0207; gamma=0.25;x=@(beta) (beta-alpha*(beta-gamma)+sqrt((beta-alpha*(beta-gamma)).^2+4*alpha*beta*gamma*A))./(2*beta);y=@(beta) x.*(1-x).*beta/gamma;t=@(beta,eps) -x+x.*y.*(alpha-eps*beta)./((A+x+y).^2);d=@(beta,eps) eps*beta.*x.*y.*(x.^2+(A+x).*x+A*alpha)./((A+x+y).^3);F=@(beta,eps) (t.^2-d);figureezplot(F,[0,1,0,1]);
