filling between lines with plus sign

Question

I want to fill between any curves with + sign in matlab. For simplicity, you can consider the unit square and I want to have + signs everywhere inside of the square. I have tried to use fill function in matlab, but that's make the region colorful but not filled with + sign. Any ideas?

Answer 1

Another possibility is to use the stipple function from Chad Greene's Climate Data Toolbox from Matlab file exchange. You can read the docs on the function here.

xx=[-10:.01:10];
yy=[-10:.01:10];
[X,Y]=ndgrid(xx,yy);
mask=zeros(size(X));
mask(X>0 & Y>0)=1;
figure
pcolor(X,Y,mask),shading flat,colorbar
hold on
stipple(X,Y,logical(mask),'density',35,'color','r','marker','+','markersize',9)
