Random index cell selection

Hi,

I want to select a random text cell in a column. Is there a specific code that I can use for selection of a random text cell in a matrix that I have imported to Matlab?

So far, I have divided the imported matrix into num, txt and raw. But, I cannot go further. You can see my codes as following:

[num,txt,raw] = xlsread('D:\Norwegian\Ordbok\Ord.xlsx');

A = txt (:,1:5);

B = txt(:,6:9);

B{ randi(numel(B)) }
