[COMSOL with MATLAB][Beginner] Geometry

Hello,
I'm new to Comsol and I'm trying to use it with Matlab. I'm just playing with the geometry right now to learn how to use it. What I would like to do is to define an object (line or surface) using a matrix of coordinates of N points. I guess I should use the function "geom2" but I don't understand how to use it properly.
Can someone help me ?
I describe differently what I want to do:
I have N points of coordinates (Xn, Yn). I want to create a line that links all this points with segments.
In a second step I'd like the points to be linked not with segments anymore but with interpolation curves.
Thanks in advance!

Hi,
To draw a polyline. Click Line from draw/specify object/Line. Line window will open. Under the coordinates there is a X edit box and y edit box. In the x edit box type all the x coordinates seperated with , like x1,x2,x3,x4,..xn and in the y edit box type all the y coordinates line y1,y2,y3,y4,...yn then from the style select polyline or a closed polyline.then click OK. The polyline is drawn.
The geom2 as far as I know is for cases when you want to draw a 2D shape and extrude to make 3D. If you want to draw a 2D on x-y plane and extrude it along z first go to draw/work plane setting/Quick and select x-y z=0 and click OK. A 2D plane will appear. draw what you like then use draw/extrude to extrude it along z.
I don't know about the second step(the interpolation curve)
Hope it helps
