Divide an area into equal sized small grids

Hi,

I am working in WSN. I have created a sensor network of size (100 * 100)..How could i divide that region into equal sized small grids..Can meshgrid be used here? how?

I’m not certain what you mean by ‘equal size small grids’, but if you want a (100x100) grid, this is one way to do it:

x = linspace(1, 100);
[X,Y] = meshgrid(x);

figure(1)
plot(X,Y,'k')
hold on
plot(Y,X,'k')
hold off

 by ‘equal size small grids’, I mean that, I want to fill up that space with squares having same size.

This plot is what the code produces:

Is that what you want?

This code should work:

NrGrid = 6;                                 % Number Of Grids
x = linspace(0, 100, NrGrid+1);
[X,Y] = meshgrid(x);

figure(1)
plot(X,Y,'k')
hold on
plot(Y,X,'k')
hold off
set(gca, 'Box','off', 'XTick',[], 'YTick',[])
axis square

The ‘NrGrid’ assignment is the number of grids created on each axis.

The new plot:

How can it be done in case of a 3D figure? like for a cuboid?
