Identify index of cell based on stringlength

I have a cell array of such:

TStr =
  1×1 cell array
    {2×1 cell}
TStr{1}(1) =
  1×1 cell array
    {'Hello... It me,  I was wondering if after all these years youd like to meet'}
TStr{1}(2) =
  1×1 cell array
    {'1800'}

I know that

    strlength(TStr{1}(2)) 
    = 4

How do I use this information to identify the index of the cell (in this case, index = 2) with stringlength of 4?

Example data:

Tstr{1}{1,1} = 'Hello... It me,  I was wondering if after all these years youd like to meet';
Tstr{1}{2,1} = '1800';

You can get the index by:

idx = cellfun(@numel,Tstr{1})==4;

Which gives:

Tstr{1}{idx}

ans = '1800'

Thanks! This is plenty of help!

If you dont mind I tagging along a more specific question...

When I run this code, I get

idx =

  2×1 logical array

   0
   1

How do I make it return 2 (the location of the cell in the cell array that has 4 stringlength)?

Pass idx into the find function

[Turlough Hughes]

The first is a logical index, the second is a linear index but both are indicating the position.

Oh I see! Thank you very much for your help!
