replace array numbers in places that are not the indices of another array

Hello, I have array_1 looks like this: array_1=[4 7 22 44 13 4 1 9 6 0 5 77 45 12];

I have another array -> array_2=3:7;

I need to write a code such that the indices of array_1 which are represented in array_2 will stay as they are and all the others will replaced by zeroe so I can get:

array_1=[0 0 22 44 13 4 1 0 0 0 0 0 0 0];

Help please! Thanks

array_1=[4 7 22 44 13 4 1 9 6 0 5 77 45 12];
array_2=3:7
array_3=zeros(size(array_1))
array_3(array_2)=array_1(array_2)
