Dear all
Currently, I am plotting the following:
u1=figure('visible','off','units','pixels','position',[0 0 1920 1080]);
t=tiledlayout("vertical");
title(t,strcat(['Exfoliated hexalayer. First layer. LLG-Heun, $t=\, \,$',num2str(time(m)),'',time_text{m},', $\alpha=\, \,$',num2str(damping(1)),'. $T=\, \,$',num2str(round(temperature(m),2)),' K, $\mathbf{H}=0$';'';'']),'FontSize',18,'interpreter','latex');
nexttile;
uimagesc(space_x,space_y,mx_1(:,:,m));
hold on
plot(geometry_tetra(:,1),geometry_tetra(:,2),'-k','LineWidth',0.5);
plot(geometry_penta(:,1),geometry_penta(:,2),'-k','LineWidth',0.5);
plot(geometry_hexa(:,1),geometry_hexa(:,2),'-k','LineWidth',0.5);
hold off
axis xy;
clim([-1 1]);
colormap(bluewhitered(256));
box on;
xlim([0 x]);
xticks([0:50:200]);
ylim([0 y]);
yticks([0:19:95]);
pbaspect([x/y 1 1]);
xtickangle(0);
set(gca,'TickLabelInterpreter','latex','FontSize',18);
t1=title(['$m_a$'],'FontSize',20,'interpreter','latex');
set(t1,'interpreter','latex','FontSize',20);
set(gca,'XTickLabel',[]);
yticks([0:19:95]);
nexttile;
uimagesc(space_x,space_y,my_1(:,:,m));
hold on
plot(geometry_tetra(:,1),geometry_tetra(:,2),'-k','LineWidth',0.5);
plot(geometry_penta(:,1),geometry_penta(:,2),'-k','LineWidth',0.5);
plot(geometry_hexa(:,1),geometry_hexa(:,2),'-k','LineWidth',0.5);
hold off
clim([-1 1]);
colormap(bluewhitered(256));
axis xy;
box on;
clr2=colorbar;
set(clr2,'TickLabelInterpreter','latex');
ylabel(t,'$b$-{\it th} spatial direction, $b \, \, \left( \mathrm{nm} \right)$','FontSize',18,'interpreter','latex');
ylabel(clr2,'$i$-{\it th} magnetization component, $m_i$','Interpreter','Latex','FontSize',19);
clr2.Layout.Tile='east';
xlim([0 x]);
xticks([0:50:200]);
ylim([0 y]);
yticks([0:19:95]);
pbaspect([x/y 1 1]);
xtickangle(0);
set(gca,'TickLabelInterpreter','latex','FontSize',18);
t2=title(['$m_b$'],'FontSize',20,'interpreter','latex');
set(t2,'interpreter','latex','FontSize',20);
set(gca,'XTickLabel',[]);
yticks([0:19:95]);
nexttile;
uimagesc(space_x,space_y,mz_1(:,:,m));
hold on
plot(geometry_tetra(:,1),geometry_tetra(:,2),'-k','LineWidth',0.5);
plot(geometry_penta(:,1),geometry_penta(:,2),'-k','LineWidth',0.5);
plot(geometry_hexa(:,1),geometry_hexa(:,2),'-k','LineWidth',0.5);
hold off
box on;
axis xy;
clim([-1 1]);
colormap(bluewhitered(256));
xlabel('$a$-{\it th} spatial direction, $a \, \, \left( \mathrm{nm} \right)$','FontSize',18,'interpreter','latex');
xlim([0 x]);
xticks([0:50:200]);
ylim([0 y]);
yticks([0:19:95]);
pbaspect([x/y 1 1]);
xtickangle(0);
set(gca,'TickLabelInterpreter','latex','FontSize',18);
t3=title(['$m_z$'],'FontSize',20,'interpreter','latex');
set(t3,'interpreter','latex','FontSize',20);
yticks([0:19:95]);
set(gcf,'color','white');
set(gca,'Units','normalized');
set(u1,'Units','Inches');
posu1=get(u1,'Position');
set(u1,'PaperPositionMode','Auto','PaperUnits','Inches','PaperSize',[posu1(3),posu1(4)]);
which gives:
I need to add some text entries, in LaTeX format, in such a way that the figure looks like:
Is there any good strategy to select the position of the 4L, 5L, and 6L so the text entries are more less centered within the definition region?

You can use the text to add the strings. You need to specify the position where you want to place the string. You may find centroids o the closed region/ polygons and place the text there.

Hi @KSSV. Thank you very much for your answer! Is there any way, using text, to specify that text string should be centered at the given set of points, instead of being used as the left bottom position of the aforementioned text? This is because, as you can see here, after finding the centroid, I have something like this:

Specify the horizontal and vertical alignment:
