Answer 1

[Walter Roberson]

YourVector(randperm(length(YourVector))

[Miriam]

great! thanks a lot!!!

[Alec Nagel]

One ) missing at the end, but thanks! :)

[SREENIVASULU REDDY KAMALAPURAM]

Thanks a lot :))

[Sakib Mahmud]

YourVector = YourVector(randperm(length(YourVector)));

[PANKAJ VADHVANI]

To shuffle vectors without saving them to a variable first, e.g. to shuffle a for-loop, I recommend adding a function like this to your repertoire:

 function v=shuffle(v)
     v=v(randperm(length(v)));
 end

e.g.

 for i=shuffle(1:10)
  disp(i)
 end

Or as an anonymous function:

shuffle = @(v)v(randperm(numel(v)));

[Peeyush Awasthi]

It's indeed an smart solution to use randperm for any vector ar an array.
