Random Selection of Each Element in Vector

Greetings,

I have a vector of 12 elements (a = [10 20 35 38 40 45 48 50 55 58 60 75]') and I want to randomly select one element at a time. How can I do that? Thank you very much.

Adam's answer is the best use of MATLAB because it returns a vector, and it does not require the Statistics Toolbox.

Answer 1

[Adam]

randA = a( randperm( numel(a) ) )

will give you them in a random order all at once. Then you can take them in turn if you wish.

how can i do that? thank you so much.

[Stephen23]

 b = a(randperm(numel(a)));
 for k = 1:numel(b)
     b(k)
 end

a = [10 20 35 38 40 45 48 50 55 58 60 75] ;
N = length(a) ;
pos = 1:N ;
idx = randsample(pos,N) ;
for i = 1:N
    a(idx(i))
end

Thank you so much. I see in my output when running your script that all elements are accessed, how can I modify your script to get only one element at a time as an ouput and not all of them? (sorry, totally new to matlab)

randsample(a,1)
