Sorting same rows & columns in two different matrices?

I have two matrices
A =
16 2 3 13
5 11 0 8
9 7 NaN 12
4 14 15 1
B =
6 NaN 3 11
NaN 16 10 0
9 3 6 12
8 14 20 1
I want to select non-zero or no NaN values from matrix 'A'. These values are placed in certain rows:columns of the matix. I want to consider those selected rows:columns from A, and select same rows:columns in matrix B (of same szie). For small matrices, it is easier to recognise but how do we do in matrices of size 92x128. Any leads will be appreciated?

A = [ 16 2 3 13
5 11 0 8
9 7 NaN 12
4 14 15 1];
idx = isnan(sum(A,2)) ;
% pick non nan rows
A(~idx,:)
