MATLAB: Random Number from -1 to 1

MATLABnumrandomrandom number generator

Hi. I want to know how to generate a random number from -1 to 1

Numbers = (1-(-1)).*rand(100,1)+(-1)
                       % ^^^^^---- number of points

You haven't looked very far, rand is what you want:

n = 2 * rand(1, 1000) - 1; %generate 1000 numbers between -1 and 1

Do you want these uniform between -1 and 1?

   r = -1 + 2.*rand(100,1);

For 1 such number

     r = -1+2*rand(1,1);
