How do you delete text data from a row if its characters are equal to or less than 3

I have a 163x1 row of text data, the data that I would like to replace with "" has 3 characters, while the data I want to keep has greater than 3 characters. Below is a section of the data:

'Trinidad & Tobago'
  'USD'
  'Turkey'
  'TRY'
  'USD'
  'Uganda'
  'UGX'
  'Ukraine'
  'USD'
  'United Arab Emirates'
  'USD'
  'United Kingdom'
  'USD'
  'United States'
  'USD'
  'Uruguay'
  'UYU'
  'Zambia'
  'USD'
  'NA'
  'BRL'
  'COP'
  'CZK'
  'EUR'

How are these data currently stored? For example, do you have them in a cell array? Or in a CSV file, not yet loaded into MATLAB?

If you have the data in a cell array:

C = {'Trinidad & Tobago'
  'USD'
  'Turkey'
  'TRY'
  'USD'
  'Uganda'
  'UGX'
  'Ukraine'
  'USD'
  'United Arab Emirates'
  'USD'
  'United Kingdom'
  'USD'
  'United States'
  'USD'
  'Uruguay'
  'UYU'
  'Zambia'
  'USD'
  'NA'
  'BRL'
  'COP'
  'CZK'
  'EUR'}

then

C = C(cellfun(@(x)length(x)>3,C))

will keep only the longer entries, while

C(cellfun(@(x)length(x)<=3,C)) = {''}

will replace the 3-character entries with empty string.
