Fetching variable from another variable

I have two sets of variables

A=

'yar12'  'hi'     'hello'   'hi'   'hello'

'yar13'   hello'  'hello'   'hi'   'hello'

'yar14'  'hi'     'hi'      'hi'   'hello'

'yar15'  'hello'  'hi'      'hi'    'hi' 

'yar16'  'hello'  'hi'      'hi'    'hello'

'yar17'  'hi'     'hi'      'hi'     'hi'

and 

B=

'yar13'   hi'     'hello'   'hello'  'hello'

'yar16'  'hi'      'hello'   'hi'     'hello'

'yar17'  'hello'  'hi'      'hello'  'hi'

The size of both matrix are different by comparing first column,i want to fetch values(2nd to 5th column) from A correspnding to 1st column of B,So i need output as

C=

'yar13'   hello'  'hello'   'hi'   'hello'

'yar16'  'hello'  'hi'      'hi'    'hello'

'yar17'  'hi'     'hi'      'hi'     'hi'

PLease provide assistance

[Walter Roberson]

[tf, idx] = ismember(B(:,1), A(:,1));
C = A(idx,:);

[Andrei Bobrov]

C = A(ismember(A(:,1),B(:,1)),:);
