Creating a linearly spaced array of a particular size

Question

I am new to MATLAB and currently working on my homework assignment. I am trying to declare the x variable as the following:

Create a linearly spaced array x of size (1 × 200) comprising values ranging from –pi to pi.

I've tried this code:

x=[-pi:200:pi];

but I'm not sure if it's the correct way to do this or not.
