How to Compare value returned by regexp and another string ?

nameF='aa.txt';
cni =regexp (nameF, '.txt', 'split');

I want to compare cni with a String by using strcmp for exemple strcmp(cni,'aa') so I converted its type by using char(cni) since cni is cell but it still returns false even they have the same value. What am I missing here ?

"What am I missing here?" &nbsp I guess you are missing that

cni =regexp (nameF, '.txt', 'split');

returns a &nbsp<1x2 cell> array and that char(cni) returns a &nbsp<2x2 char> matrix

>> nameF='aa.txt';
cni =regexp (nameF, '.txt', 'split')
cni = 
    'aa'    ''
>> char( cni )
ans =
aa

>> double( char( cni ) )
ans =
    97    97
    32    32
>>

instead use

strcmp( cni{1}, 'aa' )

or if 'aa.txt' is a filename

>> [ ~, name ] = fileparts('aa.txt')
name =
aa
>> strcmp( name, 'aa' )
ans =
     1

nameF='aa.txt';
cni =regexp (nameF, '.txt', 'split')

The result is

cni = 

    'aa'    ''

then

strcmp(cni,'aa')

gives

1   0

What is the problem here?

[Zineb EL MORCHID]

if(strcmp(cni,'aa')==1) 
msgbox('the same', 'Error','error');
else
msgbox('not the same', 'Error','error');   
end

it displays not the same

[Azzi Abdelmalek]

cni ={'aa'    ''}  is a 1x2 cell array

strcmp(cni,'aa') returns two result [1 0]; maybe what you to do is

any(strcmp(cni,'aa'))

Yes, Thank You sir .
