How can I create vector for values in the range -π < θ < π ?

How can I create vector for values in the range -π < θ < π ?

You can use linspace() to specify the number of elements you want:

margin = 0.0001; % Whatever you want.  How close to pi you want to allow.
numElements= 1000; % Whatever you want.  How many elements in your vector.
theta = linspace(-pi + margin, pi - margin, numElements);

Use colon notation, e.g.:

 T = -pi:0.01:pi

This kind of very basic MATLAB usage is introduced in the introductory tutorials:

I know this way. But I do not want -pi and +pi themselves to be included in the vector.

[Stephen23]

 S = 0.01;
 T = S-pi:S:pi-S;
