How to remove vectors values with restraints?

I'm with two distinct vectors that shouldn't have, in the same column, values that would sum up to >=1.

Ex:

A = [ 0.1 0.2 0.4 0.6]

B = [ 0.5 0.9 0.6 0.2]

Since 0.2 + 0.9 = 1.1 and 0.4 + 0.6 = 1, what I would need is a code that would turn this set of vectors into:

A = [ 0.1 0.6] B = [0.5 0.2]

How can I do that? I have no clue where to start

 A = [ 0.1 0.2 0.4 0.6]
 B = [ 0.5 0.9 0.6 0.2]

 C=(A+B)<1
 
 A=A(C)
 B=B(C)

C =

1×4 logical array

1 0 0 1

A =

0.1000 0.6000

B =

0.5000 0.2000
