Fill one vector with zeros when another vector is zero

I have two vectors A and B of same lengths. I wanto to replace values of A with zeros when B is 0. As follows:

[A] [B]

1 1

2 1

3 1

4 0

5 0

6 1

7 1

8 0

Then the new [A] will be...

[A2]

1

2

3

0

0

6

7

0

Any help will be much apreciated it.

A2=A.*(B~=0)

thank you! and what if want to delete them?

so the new vector is

[A2]

1

2

3

6

7

[madhan ravi]

nonzeros(A2)

[Francisco Anaya]

this will delete all the zeros values in A2, what i need is to delete the values in A when B is equal to zero.

[madhan ravi]

A2(B==0)=[]
