I have a data set in the range of (x[0 10], y[0 10]) so i want to plot this data in the area of 100x100 so that It can give a larger view of the data set. I want to expand this with respect to data ? how i can do this ? Need your guidance.

You don't need to change your data, just change the axes limits to zoom into the data that you want to see. Try something like this:

xlim([0,10])
ylim([0,10])

There are plenty of options, so read the documentation too:

EDIT: multiply the data by 10. This seems to be what the OP is wanting to do.

@Stephen Cobeldick, Well "limiting my plot to this axis mean i have my data in [0 10] in both axis but I want it should give me a view in [0 100] in both axis. Well the setting of limits work but it is plotting my graph in [0 10] range in both axis. But i want to expand it to [0 100] area in both axis.

if true
  colorstring = 'mbybgkkcrr';
  figure;
  hold on;
  for nodeIndex = 1:numNodes
plot( nodep(nodeIndex).x(1:end), nodep(nodeIndex).y(1:end),'*',
'color',colorstring(nodeIndex));
text(nodep(nodeIndex).x(1), nodep(nodeIndex). y(1), 'SP','Color','r' ,'FontSize',20);
text(nodep(nodeIndex).x(end),nodep(nodeIndex).y(end), 'EP','Color','r','FontSize',20);
set(gcf, 'Units', 'Normalized', 'OuterPosition', [0 0 1 1]);       
xlim ([0 10]); ylim ([0 10]);
  end
end

@Image Analyst It plot in so that the data in 0-10 range get the view of 0-100 range.

It will now take up the same real estate on my screen that the old 0-10 range did before. Is

that not the case?

The obvious answer is to multiply your X and Y values by 10. But it still seems rather bizarre to prefer to change the data rather than simply zoom the axes.
