How to divide many lines ?

Hello, need little help with one problem.

I have code which making a construction and I need to divide every line.

clc
clear
nodes=[0 0              %X-coord, Y-coord
    0 -10
    10 -12
    10 0
    20 -10
    20 0];
Nnodes = size(nodes,1); 
lines =   [1 2      %1.node, 2.node
    2 3 
    3 4 
    3 5 
    5 6 ];  
Nlines = size(Nlines,1);

and then of course I also need the correct matrices with all nodes and lines

hope, you will help me.

Thanks

Hi, since your oibjective is to split all existing lines, its sufficient to:

1. Get coordinates of the midpoints in all existing lines.
2. Add the midpoints to your original points and you have the new points array
3. Create two lines from each of the original lines, using the new midpoints.
