I am modeling a system using Simulink.
I need to make the input of the system a series of pulses (non periodic). Each pulse has a different amplitude.
For example, the first pulse has an amplitude of 5 ; the 2nd: 3 ; the 3rd: 10 ; the 4th: 1 ; the 5th: 20 ; etc.
I though that I should make a gain matrix and multiply it by the input pulse generator but it doesn't seem to work...
Any idea how to solve this?
Thanks!

If the pulse is non periodic, how do you use Pulse Generator block?
One solution is to use the Signal Builder block, you can add the pulse any way you like.
Construct variable t and y in workspace like below:
t=[0:11;1:12];
t=t(:);
y=repmat([0 0 1 1],1,6);
Then in Signal Builder block, select menu Signal>New>Custom..., put in t and y, and then you can drag the pulse to adjust the amplitude.
