How do you use randperm on a vector?

I have a vector

A = repmat(1:6, [1 4])

and I need to use randperm to randomize it. How would I do that?

Answer 1

[Kristi]

A = repmat(1:6, [1 4])
B = A(randperm(24))

[Guillaume]

B = A(randperm(numel(A))

would be a lot better since it will work regardless of the size of A. As a rule avoid hardcoded constants, particularly as it's trivial to obtain the number of elements in A.
