MATLAB: Delete elements in cell array with certain length

how can I delete all elements of a cell array that have less then for example 5 elements inside. 

result{1}= 1
result{2}= [2 3 4 5 6 7 8]
result{3}= [9 10 11 12 13 14 16 17 18]
result{4}= [19 20 21]

In this example I want to delete result{1} and result{4}, because they have less than 5 elements inside.

With this topic ( matlab length of each element in cell array) I know how to get the length of each element, but how is possible to delete elements of a specific length?

Solution

  • Just choose the ones that have more than 4 elements by logical indexing:

    result = result(cellfun('length', result) >= 5);
