solution:
A=[11.3 , 10+5i , 32 , 50+48i , 9 , 21+15i ,16 ]
onlyreals=A(imag(A)==0)
edit:
with cell array
A={ [ 1, 2+3i, 4, 5+6i ] , [7, 8+9i, 10, 11+12i ] , [13+14i, 15 ,16 ,17] };
B=cell(size(A));
for k=1:numel(A)
B{k}=A{k}(imag(A{k})==0);
end
disp(B)

what about the cell array?
A={ [ 1, 2+3i, 4, 5+6i ] , [7, 8+9i, 10, 11+12i ] , [13+14i, 15 ,16 ,17] }
