Hello, is there a matlab function that picks a random entry from a vector? I solved the problem with
i=randperm(length(vector),1),
entry=vector(i).
But i wondered if there is a more elegant solution. Thank you

entry = vector(randi(length(vector)));

If you have the Statistics and Machine Learning Toolbox, you can use the datasample function.
