How can use isempty function or another function in matlab??

i didn't know how to use isempty function

for example:

the first matrix from simulation=[18 1 0 0 0;12 0 0 0 1;15 1 1 0 0] and the second matrix from simulation=[25 0 0 0 0;30 1 1 0 0;14 0 0 1 0] and the thierd matrix from simulation=[50 1 0 0 0;12 0 0 1 0;24 1 1 1 0] I used the following function :idxfun=@(x)find(ismember(x(:,2:end),[1 0 0 0],'rows')) :::::: a=the first matrix(idxfun(the first matrix),:)the answer is as follows: 18 1 0 0 0 the second matrix answer is:: empty matrix:0-by-5 then the simulation stop!! what i want is to make the simulation continue and go to the next matrix and in this example the answer will be 50 1 0 0 0
