Identification of sampling frequency I have the following vector:

%create vector of sampling
t=0:pi/100:2*pi;
x=sin(t);


What is the sampling frequency (of this vector) ?

Thanks
A discrete sine wave is defined as
$$\sin (2\pi  f n)$$
Now your index is n=2*pi*(0:1/200:1). This means your sampling frequency is 200Hz.
