How to load matcont data file and plot

I want to plot the data file of a two parameter bifurcation diagram.

clear all
format long
set(0,'DefaultAxesFontSize',20);
figure;
load('H_H(1).mat')
load('H_H(2).mat')

In both the mat files, the x Array contain the two phase variables and two parameters. Identifying the parameters in x, I want to plot the diagram where the two parameters will be along x and y axis, respectively.

• How to load only 'x'?
• What would be the plot comand?

It is not clear what you want to plot?

format long
set(0,'DefaultAxesFontSize',20);
figure;
H1_struct = load('H_H(1).mat', 'x');
H1_x = H1_struct.x;
H2_struct = load('H_H(2).mat', 'x');
H2_x = H2_struct.x;

subplot(2,1,1);
plot(H1_x(4,:), H1_x(5,:)); title('H1 x 4 vs 5');
subplot(2,1,2);
plot(H2_x(4,:), H2_x(5,:)); title('H2 x 4 vs 5');
