MATLAB: Delete values in a vector based on another vector

Question

I have two arrays

I have two data vectors A (consiting of an array of 90872×2 double) and B (consisint of an array of 90872×2 double). As follows:

A(:,1)= A(:,2)= B=

1 2 1

1 2 1

1 2 1

2 1 1

1 1 0

1 1 0

1 1 1

2 1 0

2 1 0

2 1 0

2 1 0

2 2 1

I want to delete values in A when B is equal to zero. Therefore, my new A will be:

A(:,1)= A(:,2)=

1 2

1 2

1 2

2 1

1 1

2 2

Any help
