multiple conditions in matrix

I am receiving this error while applying multipe conditions in matrix

Code:

C= [rand(100,1),randi([0,2],100,1),randi([0,2],100,1),randi([5,12],100,1)]

d=C(C(:,2) == 1,: && (:,3) == 2, :)

Answer 1

[Simon Chan]

Do you want this?

d=C(C(:,2) == 1 & C(:,3) == 2)

[Jonas]

probably

d=C(C(:,2) == 1 & C(:,3) == 2,:)

yes exactly
