How to remove the values in vector 'B' corresponding to 'NaNs' in vector 'A'?

Hello every one, I have two vectors as a sample

A=[10 12 15 NaN 20 30 46 NaN 12 10 NaN 9 8 7 8 NaN 51 Nan 24]
B=[11 73 24 36 47 18 29 31 52 44 33 22 28 16 15 13 19 18 13]

I can delete the 'NaNs' from vector 'A' by using a function

A(isnan(A)) = [];

but I also want to delete the values in vector 'B' corresponding to 'NaNS' in vector 'A'. I want to get

A=[10 12 15 20 30 46 12 10 9 8 7 8 51 24]
B=[11 73 24 47 18 29 52 44 22 28 16 15 19 13]

I do not know how to get it. Any help will be appreciated.

Thanks
