Compare vectors and save the values

Hi! I have

T=[1 1;1 2;1 3;1 4;256 2;259 2;263 2;268 2;315 2;330 3;335 3;336 2;337 2;338 2;339 2;340 2;345 2;345 3;349 2;354 2];

S= [1 345 360]

I want to compare the values in S (1, 345, 360) with the values of first column of T: if there is a corrispondence, I want to save the row.

I want output C=[1 1;1 2;1 3;1 4;345 2;345 3]. Can you help me?

idx = ismember( T(:,1), S );

C = T( idx, : );
