PMSM equation according to the MathWorks document doesn't match the equation elsewhere. According to the books the evaluation for electromagnetic torque should be:
Te = 1.5*PM.p/2*(PM.Flux*u(1)+(PM.Ld-PM.Lq)*u(1)*u(2))
However, according to MathWorks document:
Te=1.5p[λiq+(Ld−Lq)idiq]
Why is the "/2" been omitted in the MathWorks equation for PMSM?

In the equation provided, the term 'p' is number of poles. However, while modeling a PMSM in Simulink, 'p' is considered as number of pole pairs. Hence the "/2" term is omitted.
Te=1.5p[λiq+(Ld−Lq)idiq]
