How to generate a random 2x2 matrix with values in the range −1 to 1

Hi, I'm new to matlab and trying to generate a random 2x2 matrix with values in the range -1 to 1.

Thank you for your time.

This works:

M = 2*rand(2)-1;

[N/A]

Unfortunatly that creates a matrix with 0.9195, 0.1705, -0.3197, -0.5524. Instead, I need something like 1, -1, 0, 1

If you want integers only, use the randi funciton:

M = randi([-1 1], 2);

[N/A]

Excellent, that works fine. Thank you.
