The problem was that Ts (1/Sampling Frequency) was not smaller enough which means the Sampling frequency was not big enough. The Sampling Frequency should have been at least bigger than 2*pi*F0 and Ts should have been smaller than $ {1/(2*pi*F0)} $,

F0 =13; 

T0 =(1/F0); 

Ts = 0.0001;

t  = 0:Ts:13*T0; 

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

plot(t,x)

%F0 =13; 

%T0 =1/F0; 

%Ts = 0.07;

%t  = 0:Ts:13*T0; 

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