Plot the trapeoidal waveform using given equations

F(θe) 
1                     0 ≤ θe < 2π/3 
1− 6/π(θe − 2π 3 )    2π/3 ≤ θe < π 
−1                    π ≤ θe < 5π/3 
−1 + 6/π(θe − 5π 3 )  5π/3 ≤ θe < 2π

syms theta
y=piecewise(...
    0<=theta<2*pi/3,1,...
    2*pi/3<=theta<pi,(1-6/pi*(theta-2*pi/3)),...
    pi<=theta<5*pi/3,-1,...
    5*pi/3<=theta<2*pi,(-1+6/pi*(theta-5*pi/3))...
    );
fplot(y,[0 2*pi]);

[Mantavya Vashistha]

thank you very much

can you help me to implement this waveform on generating back emf tapezoidal waveform on simulink

I have been made a simulink model to calculate wm

I have to find ea,eb and ec

[Vladimir Sovkov]

I am not much experienced in Simulink but I think that the overall programming linguistic does not differ very much.
