WebYou can invoke the function and create a structure with a field containing the value 1 with the command: myStruct (1) ans = struct with fields: Afield: 1 However, if you want to return the field value directly, you can index into the function call result with the command: myStruct (1).Afield ans = 1 WebAug 15, 2024 · Logical indexing with structures is similar to other logical indexing in MATLAB. The one difference is when you are trying to use fields in the equivalence statement. This is because s.field1 has multiple outputs. To get around this, simply put brackets [] or {} around s.field1 in order to get one output that is an array or cell. Theme …
