How can I choose a random row from a specific multidimensional array?

Hi,
I have a multidimensional array X=(50,9), and I want to choose a random row of 50 exist rows in an array.
First row in this array is just scalar numbering from 1 up to 50, I do not know if this can help to pick a random row based on the first row value or not!
Thanks in advance!

randomRow=X(randi(50),:);

That was so quick : )
Thanks a lot.
Is it possible to replace the length of the array rows (50) with flexible statement to specify the number of rows in any array?
I just ask to generalise the answer rather than specified a specific value
Thanks again : )
