Retaining the length of matrix after difference

A matrix

A1 = [2 4 5 6 7 8 9 10 11 3 ];

A2 = [ 2 7 10];

A1 and A2 has some coomon values. I want to find the matrix A3 with no similar value of A1 and A2 and the length A1 must be retained.

A3 = [0 4 5 6 0 8 9 0 11 3];

Length will be equal to A1. but values same as in A2 will have 0 in there place

[Voss]

A1 = [2 4 5 6 7 8 9 10 11 3 ];
A2 = [ 2 7 10];

A3 = A1;
A3(ismember(A1,A2)) = 0

A3 = 1×10

0 4 5 6 0 8 9 0 11 3
