I'm having a hard time to include a global legend in tiledlayout function. Does anybody has the same problem like me and have a solution?
for eg. I need to plot 2x2 plot and all of them need to have same global legend. While trying, I get my legend on a last plot!!! I want to display my legend in the southoutside of my plot (i.e. it should be at the middle of my last last two plots).
Any help or suggestion would be highly appreciated.

Global legends can be created by specifying the object handles that exist in any subplot (created by subplot or nexttile) within the same figure.
As of r2020b, you can specify the location of a legend relative to the TiledLayout.
This demo places the legend South of the 2x2 tiles.
figure()
colors = [winter(3);summer(3);autumn(3);copper(3)];
subPlotNames = 'ABCD';
h = gobjects(3,4);
tlo = tiledlayout(2,2);
for i = 1:4
ax = nexttile;
h(:,i) = plot([0,1],[.66;.5;.33].*[1,1],'LineWidth',4);
text([.1,.1,.1],[.66;.5;.33],{'1' '2' '3'},'VerticalAlignment', 'Bottom')
set(h(:,i), {'DisplayName'}, compose('%s %d',subPlotNames(i),1:3)')
title(subPlotNames(i))
end
set(h(:), {'Color'}, mat2cell(colors,ones(12,1),3))
lg = legend(ax,h(:),'Orientation','Horizontal','NumColumns',6);
lg.Layout.Tile = 'South'; % <-- Legend placement with tiled layout

Look at sgtitle which does exactly this.

Not a relevant answer. You have mistaken title and legend... So what is the correct answer for a legend?

Legend needs a axis object as a target hence it cannot be attached with tiledlayout object itself, hence creating a global legend by this method is not possible. You can modify Legend property "legend.Position" to have legend at the desired location.
Also I found a similar question where subplot is used in place of titledlayout, please refer below for the link:
