Detecting a particular word in a cell vector

 Dear all, 
I have a matrix whose first column is :
    'MAR'

'   POPSIZE'

    'OTHTOTAL'

    '   CONIZE'

    '   POPIZE'

    'MAR'

    '   POPULAR SIZE'

    'OTHOTAL'

    '   CONSIIZE'

    '   POPUZE'

    'MAR'

    'PRODGORY'

 I want to detect if the above column contains the string element  ‘MAR’

thanks

eg

A = {'MAR'
    '   POPSIZE'
    'OTHTOTAL'
    '   CONIZE'
    '   POPIZE'
    'MAR'
    '   POPULAR SIZE'
    'OTHOTAL'
    '   CONSIIZE'
    '   POPUZE'
    'MAR'
    'PRODGORY'}

out = any(ismember(A,'MAR'));

or

out = any(strcmp(A,'MAR'));

STRCMP is faster.

 see if any(strcmp(M,'MAR')) works for you, if there is MAR it shows 1 else 0

 Example: If M = {'MAR'
    'POPSIZE'
    'OTHTOTAL'
    '   CONIZE'
    '   POPIZE'
    'MAR'
    '   POPULAR SIZE'
    'OTHOTAL'
    '   CONSIIZE'
    '   POPUZE'
    'MAR'
    'PRODGORY'}
 use strcmp(M,'MAR')

I would use a regexp. http://www.mathworks.com/help/techdoc/ref/regexp.html Perhaps with a 'match' option, depending what you want as an output.

    test = { 'MAR'
    '   POPSIZE'
        'OTHTOTAL'
        '   CONIZE'
        '   POPIZE'
        'MAR'
        '   POPULAR SIZE'
        'OTHOTAL'
        '   CONSIIZE'
        '   POPUZE'
        'MAR'
        'PRODGORY'};
    regexp(test,'MAR')

all of you three were correct and I thank you
