I am trying to set the 2D graph axis label using h.XTickLabel = dx*h.XTick. Problem comes when I am stretching the graph.

First I plotted the graph ticks as 0,80,160,240,300, using above command. However when I am stretching the figure, axis numbers changes. Matlab automatically created almost twice of subdivisions and now the axis ticks are 0,80,160,240,300,0,80,160,240.

You could try

f = gcf;
f.ResizeFcn = 'h.XTickLabel = dx.*h.XTick;';

This will call

h.XTickLabel = dx.*h.XTick;

every time the figure resizes. However, if you would like to do this to more than one graphics object, you should put it in a separate function and put that function in the ResizeFcn.

If the variable dh is not in the workspace, you will have to save it. You could save it in the axes's UserData like this:

nh=100; nv=200;
dh=10; dv=5;
mat=rand(nv,nh);
subplot(2,2,2); imagesc(0:nh-1,0:nv-1,mat);
h=gcf;
ax = gca;
ax.UserData = dh;
g=get(gcf,'children');
h.SizeChangedFcn = 'set(gca,''XTickLabel'',get(gca,''UserData'').*get(gca,''XTick''));';
clear

However, for reasons of flexibility, I would recommend you write a separate function, since the above method will only work on a single subplot:

function axTickUpdate()
AX = findobj(gcf,'type','axes');
for i = 1:length(AX)
    ax = AX(i);
    ax.XTickLabel = ax.UserData.dh.*ax.XTick;
end
end

You can then create the figure like this:

nh=100; nv=200;
dh=10; dv=5;
mat=rand(nv,nh);
subplot(2,2,2); imagesc(0:nh-1,0:nv-1,mat);
h=gcf;
ax = gca;
ax.UserData.dh = dh;
g=get(gcf,'children');
h.SizeChangedFcn = 'axTickUpdate;';
