I have a matrix "A" with size 4x8 char and having values:
'01:04:00'
'01:03:00'
' '
'01:01:00'
I want to identify the index of empty char. I.e. 3rd one.
I tried,
% first one
A == ""
% second one
A == ''
% third one
isempty(A)
% forth one
isspace(A)
% fifth one
A == ' '
% sixth one
A == " "
% everything shows zero output.
Can anyone please help?
Any help will be greatly appriciated.

M = [...
'01:04:00'
'01:03:00'
' '
'01:01:00'];
strcmp('',cellstr(M)) % CELLSTR removes trailing whitespace characters.
cellfun(@isempty,cellstr(M)) % CELLSTR removes trailing whitespace characters.
all(M==32,2) % match space character only.
all(M==' ',2) % match space character only.
all(isstrprop(M,'wspace'),2) % match any whitespace character.
