Let us learn how to find out if a string array is empty or not using the ‘isempty’ function. isempty function in MATLAB can also be used for a string array. So, this can be concluded that an array with all the elements as zero, is not considered as an empty array.

As we can see in the output, we have obtained logical 0 for an array of dimension 3 x 3 and all the elements as ‘0’. Calling the isempty function using the input array ‘X’. Let us now take an array with dimensions that are not equal to zero, but all its elements are equal to zero.Įxplanation: Defining the input array with dimensions 3 x 3 and all the elements as zero. A very important point to remember here is that ‘isempty’ function identifies empty arrays AND NOT the arrays with all the values as zero. As we can see in the output, we have obtained logical 0 for an array of dimension 3 x 3, as expected by us. We will be taking an array of dimensions 3 x 3 and see how the ‘isempty’ function works.Įxplanation: Defining the input array with dimensions 3 x 3. Let us now take an array with dimensions that are not equal to zero and see how the results vary. As we can see in the output, we have obtained logical 1 for an array of dimension 0 x 4, as expected by us. Let us take an array with dimensions 0 x 4 and see how the ‘isempty’ function works.Įxplanation: Defining the input array with dimensions 0 x 4. As we can see in the output, we have obtained logical 1 for an array of dimension 3 x 0, as expected by us.
