MATLAB: How to randomise numbers in a vector

Question

Dear all,

Suppose I have this vector x= [1;2;3;4];

How can I randomise it? (i.e. create different combinations of 1, 2, 3 and 4)

Thank you very much in advance, Bianca

Answer 1

See doc randperm:

x = [1;2;3;4]
y = x(randperm(numel(x)))

If this is time-critical, use FEX: Shuffle .
