I want to colour the lower portion of curve by red and broked curve and upper part of the curve by black as shown in the fig attached.

Code

format long
set(0,’DefaultAxesFontSize’,20);
figure
load(‘EP_EP(1).mat’,’x’); %load only x
idx = x(3,:)>=0.16 & x(3,:)<=0.305003;
plot(x(3,:),x(1,:),’k–‘, ‘LineWidth’,2); %middle unstable equilibria broken line
xlabel(‘$a$’,’FontSize’,20,’interpreter’,’latex’,’FontWeight’,’normal’,’Color’,’k’);
ylabel(‘$b$’,’FontSize’,20,’interpreter’,’latex’,’FontWeight’,’normal’,’Color’,’k’);
