Open in MATLAB Online Hello everyone, I have a structure with quite some fields and I want to check, if any of the fields are empty. Is there a way to do this without checking for each field individually? Currently I have an if statement with many ORs to do this: ...
This feature probably doesn't exist, but I thought I'd ask. Is there a way to check if a certain variable or field in a structure is called? I'm reading through a very large existing code, and rather than trying to step line by line (which is what I'm currently doing), it would...
There is no MATLAB function that examines every level of a structure of structures, or nested structure, to determine if a field exists. The 'isfield' function examines only the top level of a nested structure. To determine if a field exists at any other level, yo...
The std::string class has a built-in method empty() to check if the given string is empty or not. This method is of type bool and returns true when the object does not contain characters. The empty() method does not take any argument and implements a constant time complexity function....
