MATLAB: How to make a random vector with intergers

integerMATLABrandirandomvector

Hello, I was wondering how I could make a random 3 dimensional vector in Matlab with each value being an integer between -9 to 9?

randi([-9,9],3,1)

Hi,

use

x = (2*rand(1,100)-1)/10;

Best regards

Stephan

idx = [1,2,4,7,8];
out = zeros(10,1);
out(idx)=rand(numel(idx),1);
