How to create a vector of randomly selected elements from a matrix?

I am trying to create a one dimensional vector of size n from randomly selected elements of a matrix. I am not trying to select a random row or a random column from the matrix. I am just trying to create a vector from random matrix elements and have the size of my vector determined. For example:
A = [1 2 3 4 5; 6 7 8 9 10; 11 12 13 14 15];
And I'm looking for something like the following if I wanted a vector of size 6:
B = [15 2 13 8 1 10]
I tried using "datasample" but that just created another 2D matrix instead of a one dimensional vector. Any ideas?
Thanks for the help!
