In the code used below the sampling frequency is too low. Hence the time interval between any two samples is very high. This results into skipping of certain values of the signal.

code with bug

F0 =13;

T0 =1/F0;

Ts = 0.07;

t  = 0:Ts:13*T0;

x = real(exp(j*(2*pi*F0*t-pi/2)));

plot(t,x)

code without bug

just increase the sampling freq or in other words decrease the sampling time

F0 =13;

T0 =1/F0;

Ts = 0.07/100;

t  = 0:Ts:13*T0;

x = real(exp(j*(2*pi*F0*t-pi/2)));

plot(t,x)
