Answer 1

[Pedro Villena]

Use a Sine Block, and configure it with:

• Amplitude: -1
• Phase: -pi/2

[Azzi Abdelmalek]

Pedro how your answer is different from mine?

[Daniel Shub]

Azzi I agree that this answer is essentially the same as your answer and it appears to have been posted long enough after your answer that it is unlikely that Pedro was working on it while you before you posted your answer. That said, I am removing the flag because I don't see anything that can be done as a moderator with duplicate answers.

[Azzi Abdelmalek]

It does'nt make sens to repeat an answer, I've flaged it because it was almost copy/paste. I think Matlab answer editor should delete such clear duplicate answers.

Answer 2

[Azzi Abdelmalek]

It's one block: a sine wave block, you will find it in Simulink\Sources

Thanks Azzi ,if it is cos(wt),what must be done

[Azzi Abdelmalek]

 cos(wt)=-sin(wt-pi/2)

the set

• Amplitude = -Amp
• Phase(rad) = -pi/2

Azzi how can i perform this in simulink
