I would like to generate triangle signal starts from 0 degree and stops at 60 degree and then starts at 120 degree and stops at 180 degree for half cycle sine wave reference, and then it is repeat itself. If possible by coding or simulink. The attached picture would explain the required triangle wave.

Hi, I have used that, but it generate normal triangle wave. Do you know how to generate triangle with variable frequency or as I asked above, please?

Hi Ali,
for your problem, sawtooth() function does not work. Instead you'd need to employ triangular pulse generator function tripuls() (see the link:https://www.mathworks.com/help/signal/ref/tripuls.html)
Sub-divide the time space into 6 subsections t1 = [0, 60]; t2 = [50, 120]; t3 = [...], ..., t6 = [300, 360]; generate triangular pulse where you need (section 1, 3 and reversed ones in section 4 and 6).
Good luck
