MatLab modelling coaxial network

[Orange]

Is it possible to make a model of cable tv network (coaxial part) in
MatLab? I would like to draw amplifiers, splitters and lines so that
it could calculate signal level at certain points. Is any other
program better for that?

Yes. Obviously. However, probably not the best method.

Any spice can analyse transmission lines. Hint: SuperSpice

OK, thanks Kevin.

SuperSpice is for very precise analysis, so it does seem a bit
complicated for me. I just need some very simple math like this:
signal at home=signal at spliter-3,7dB, etc. and it should be able to
draw spliter as rectangle. The only complex problem would be that line
attenuation depends lineary of its length, but that is not necessary.

Can you tell me how to do it in SuperSpice or if there is a link
explaining it?

a spreadsheet (OpenOffice, Excel..) ?

I've tried Excel but its too hard to draw in it. MathCAD has done
those calculations for me, but it also lacks drawing tools (its better
than excel whe working with variables). The bitmap can be imported
in MathCAD but that is not good solution.
Do you have any other ideas?
