Strings: delete rows with empty values

I have a very large string array (part of it is shown below), and sometimes the secound column contains "empty" values. I would like to delete each row whose second column is empty.
"laterite-00047" "" "zeros(0,1)"
"laterite-00048" "" "zeros(0,1)"
"laterite-00049" "204186,54901" "204186"
"laterite-00050" "204186,54901" "54901"
"laterite-00051" "" "zeros(0,1)"
"laterite-00052" "204186,54901" "54901"

a(~any(cellfun('isempty',a),2),:) % where a is your string array

Alternative (faster):
a(~strcmp(a(:,2),""),:)
