How to combine input functions

I am trying to write a code for a transfer function, I have to use an input signal of a half sine wave with a period of 0.3s so from 0s to 0.15s this needs to be the input signal, then from 0.151s to 10s the input function should be 0. I know you can use gensig for the sin function but I cant figure out how to combine the two inputs for the response.

Thanks for your help!

te=0.3
fe=1/te
t1=0:.001:0.15
y1=sin(2*pi*fe*t1)
t2=0.151:0.001:1
y2=t2*0
t=[t1 t2]
y=[y1 y2]
plot(t,y)

%or

te=0.3
fe=1/te
t=0:0.001:1
y=(heaviside(t)-heaviside(t-0.151)).*sin(2*pi*fe*t)
plot(t,y)

ah was trying to do this sin(wt)*t haha. thanks for your help! it worked perfectly
