Matlab 7.8.0 (R2009a)

<<PLS help me out, the problem is that i do not scope the desirable curve!!>> Grateful for your help!
I want a sin curve and i extract a line.!
Any suggestions??

Below i am writing down my followed steps

open comsol with matlab -> select 2D in space dimension -> in the list Comsol Multi>Plane stress>Transient analysis.
->specify a rectangle object -> from options menu i choose Constants and i write load = 1000.
->from the physics menu subdomain settings the defaults, -> to Boundary Settings i choose 1=fix and 4>load>Fy=load (the constant)

->i mesh it
->i solve it for times 0:1:5
->file->export->simulink model

SIMULINK export
linearized dynamic
on variables tab -> input=load
output y1= point 3 total displacement

and ok!
