Hi,

If it is possible from the viewpoint of Matlab.

Again, an iterative algorithm (in Matlab) is given by Aydin, Demirel (2004). Please contact the authors to get access to their m-Files. I don't have Matlab Code, that I can share.

2. Is there any example file to adjustment the planned, not large network where measure the angles and lines? The site in the examples I have not found. I would love to see.

You can download an example for some days here: example.zip

Have a nice weekend
Micha
