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'

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