2, 1, and 6 are the first 3 elements of the double array A and I want only them to be 1 in the resulting logical array B (and zero for the rest).

Double array A is [2 1 6 7 3 5 4]. How can I convert it to a logical array in a way to get 1 for the first (for example) 3 elements and 0 for the rest. i.e., B = [1 1 0 0 0 1 0]. I apologize for the very basic nature of this question but unfortunately couldn't find any answer for it!

A = [2 1 6 7 3 5 4];
B = ismember(sort(A),A(1:3));
