WebMATLAB provides us with an ‘isempty’ function to check if the array is empty or not. Further, we can also check the same for a string vector by passing it as an argument to ‘isempty’ function. An important thing with ‘isempty’ function is that it checks for empty arrays, which should not be confused with arrays containing all zeros. WebMar 31, 2012 · Sep 20, 2012 at 16:54.
