I have sine wave bx is simulink,is there any box for triangular wave available,else please tell how to generate triangular wave in simulink of equal amplitude and time

generate your signal in matlab command then use a from workspace block with variable name ty
ts=0.1;
t=-3:ts:3
y=repmat(max(t)-abs(t),1,10)
t=-3:ts:-3+length(y)*ts-ts
ty=[t' y']

Azzi Abdelmalek: i didn't get how you did that, can you please elaborate a bit how to and which block i have to use in matlab, and where to put these code, newbie in matlab :|

Hi, the triangle generator does not exist but you can create your own.
My tip is to create a pulse signal (pulse width =50%) and adding a negative offset (typically the half of the amplitude you want).
If you want a triangle signal between [0 1] then you have to set:
pulse amplitude : 4 offset : -2
Then you have a pulse varying between [-2 2] You just have to integrate this signal and you will get a nice triangle signal varying between [0 1] ;)

how can i get a triangular wave varying from -ve value to a +ve value??

If you have another problem, I suggest to post another question
