I'm plotting three sets of data with the code
if true
plot(x_1,y_1,x_2,y_2,x_3,y_3) %Layered plot
xlabel('X')
ylabel('Y')
title('Particle Trajectory')
legend('Particle 1','Particle 2','Particle 3')
end
The data set x_1,x_2 is just the origin 0,0 in every component.
How can I include a solid dot at the centre of the plot and include this in the legend?

I am not certain what you want to do.
Try this:
x = [-1 1 -1 1];
y = [-1 1 1 -1];
x1 = 0;
y1 = 0;
figure(1)
L1 = plot(x1, y1, 'pg', 'MarkerSize',10, 'MarkerFaceColor','g');
hold on
L2 = plot( x, y, 'ob', 'MarkerSize',10, 'MarkerFaceColor','b');
hold off
legend(L1, 'Centre')
Ax = gca;
Ax.XAxisLocation = 'origin';
Ax.YAxisLocation = 'origin';
axis([-1.5 1.5 -1.5 1.5])
grid on
Experiment to get the result you want.

In my example code, the (x1,y1) dot is at the centre, at (0,0), and has its own legend entry.
