How to change resolution to every other point?

Hello good day,

I would like to know how to change the resoulation of my grid to every other grid point.

I have been looking into how to change it but haven't been anywere.

% load the file named XBeach_masonboro_grid.mat   
    load XBeach_masonboro_grid.mat
    figure()
% plot the topobathymetric surface (z) as a function of space (xgrid, ygrid)
   pcolor(xgrid,ygrid,z)
   title ('Masonboro Island Grid')
   grid on
   shading flat 
   

I am able to get the plot to show, but do not know how to change the resoulation to every other grid point.

Thank you!

res = 2;   
pcolor(xgrid(1:res:end,1:res:end),ygrid(1:res:end,1:res:end),z(1:res:end,1:res:end))

will only plot every other point, in both the x and y dimension (and you could make res an even large value if you want).

Is that what you mean?
