How to judge the data in a cell is 'invalid'

Question

           ''    [  2281]    [  2520]    [8]
           ''          []          []     ''

Like above data in my cell array. How do I determine the second row is invalid? I tried isempty(), but the result is not optimal.

Answer 1

Use cellfun and all along columns with isempty as follows,

>> invalidRow = all(cellfun(@isempty,C),2)

invalidRow =

     0
     1
