One half sine wave simulink

Hi. I'm trying to simulate using Simulink a quarter car model as it passes over a obstacle. My problem is that the obstacle has the shape of a single half sine wave as the one find in the attachment. How do I optain this in Simulink?

Thank you

Create a file filename.mat

A=1;
T=2*0.01;
f=1/T;
t=0:0.001:0.3;
idx=t<0.1 |  t>0.11;
y=A*sin(2*pi*f*(t-0.1));
y(idx)=0;
yt=[t;y];
save filename yt

In simulink add a from file block with the name: filename

Hello, I also want to have this input but I didn't understand how to make the m-file and import it into simulink using from data file. Can you explain more please?
