How to Search Blank Line ?

Hi- Everyone

I use 'isempty' to find an empty line.

But there is a problem

The left Side File, detect Line 4

The right file is undetectable. 'Isempty' can not be detected if there is a space

Is there any way to detect both cases?

(left file) (right file)

Assuming a cell array

line_is_blank = cellfun(@(S)isempty(strtrim(S)), YourCellArray)
