Hi,
I have a cell that contain several columns among them one text column (e.g., Person names). How can I check that the there is no duplicate names inside this column (If there is a duplicate names just assign duplicateName=true).
Thanks

Hi,
You can use the " hist " functions and the unique functions to determine if there are any duplicate values in your columns. Below is a sample code snippet:
arr = [5 3 1 5 6];
u = unique(arr);
n = hist(arr, u);
result = arr(n > 1);
Hope this helps.

duplicateName = (numel(unique(C(:, index))) == size(C, 1))
[EDITED: Parenthesis fixed]

In your question you wrote:

Then index is the index of the column, which contains the text. If C is this column already, use:
numel(unique(C)) == size(C, 1)
