Not a string after textscan in Matlab

I am reading a string of the form: Text1_Text2_Text3_Text4. I do a textscan with the delimiter "_":

myString = textscan('Text1_Text2_Text3_Text4', '%s', 'delimiter','_');

output:

'Text1' 'Text2' 'Text3' 'Text4'

This is a char array. To transform it to a String I use myString = myString{1}. I want to know the size of the second index -> numel(myString(2)); But MATLAB always returns 1. Where am I wrong? Thanks in advance.

P.S. It works if I do

myString = myString{1}(2); myString = myString{1};

But I would need a lot of variables if I also want to know the size of index 1, 3 or 4 so there must be an easier way.

To know the size of all strings:

>> sizes = cellfun(@numel, myString)

>> sizes =

     5
     5
     5
     5

To know the size of the k-th string only:

>> k = 2;
>> numel(myString{k})

>> ans =

     5
