intersection of two tables question

Hello,

I have 2 cell arrays of the following form:

A = {1,2,3;'a','b','c';'e','f','g'};
B = {'x','y';[],[];'z','v'};

and I want to create a third cell array with the content of A, but with only those rows that are not empty in B. What is the most efficient way to do that?

The result should be:

C = {1,2,3;'e','f','g'};

Help is greatly appreciated

"Great! Thank you very much. Can you tell me as well how I get the exact inverse, I mean all entries of A where B is empty?

Regards!"

Yes, just take off the ~.

A(all(cellfun('isempty',B),2),:)
