Any way to get "Invalid or deleted object" error message to include which object was invalid?

1 回表示 (過去 30 日間)
Example:
Invalid or deleted object.
Error in * (line 70)
AB.w = obj2.w*obj1.w - dot(obj2.v, obj1.v);
It would be useful to know if AB, obj2, obj1, or one of the associated properties is the deleted object without having to go into the debugger. I believe MATLAB should know which object it errored out trying to access, so is there a way to get MATLAB to tell me this info?

Send a feature enhancement request to them. Several years ago we'd simply get an "index out of bounds" error if you tried to access m(9) when m had only 5 elements. Now the error message is more explicit and tells us what index you tried to access and the length of the vector, so it is possible to have improved error messages.

Wanted to make sure I wasn't missing an option to accomplish this before making a request. Glad to know such requests have been handled well in the past, too.

Set a breakpoint there, at that line. Then hover the cursor over obj1 and obj2. If they are defined, you'll see a pop up with their value, and you'll see them listed in the workspace panel. If they are not defined, there will be no popup upon hovering, and no variable listed in the workspace panel.
