a=[1;2;3;44;15;6;7;82;9] , b=[1;2;3;3;3;3;1;3;3] and c=[14;28;36;44;5;6;12;21;19]. I would want use this selection criteria; select only the elements of b which are =3 and their corresponding values in a and c.
How can I trim this data down to a=[3;44;15;6;82;9], b=[3;3;3;3;3;3] and c=[36;44;5;6;21;19]?

This works:
a=[1;2;3;44;15;6;7;82;9];
b=[1;2;3;3;3;3;1;3;3];
c=[14;28;36;44;5;6;12;21;19];
a3 = a(b == 3)
c3 = c(b == 3)
