How to find pores of line network?

Hello everyone!!

The following code creates random lines from a set of random points.

How can I find the pores?

for Nlines=50:50:600
     nnl=nnl+1;
     nLinesarray(nnl)=Nlines;
Lx=10;
Ly=10;
for nlstart=1:Nlines-1
 for nl=nlstart+1:Nlines
      xc(nc)=(yo(nl)-yo(nlstart))/(slope(nlstart)-slope(nl));
      yc(nc)=slope(nl)*xc(nc)+yo(nl);
      nc=nc+1;
 end
end
Npointsarray(nnl)=nc-1;
Npoints=nc-1;
nc1=0;
for np=1:Npoints
    if xc(np)>0 && xc(np)<10
        if yc(np)>0 && yc(np)<10
             nc1=nc1+1;
            yc1(nc1)=yc(np);
        end
    end
end 
Npointsregion(nnl)=length(xc1);

 end

Hi @yanqi liu what do you mean?

We are not able to see any plot from the code. Can you show us a pictorial example of your expectations? Also include the plot in the given code.
