About criteria of "expensive pass by value"

Hi, there.

Cant I set the criteria of "expensive pass by value"?

when I write the code... sometimes I use structure instead pointer of structure. The size of structure is 13 bytes..

But Bug finer got ths line which has to be correted...(expensive pass by value)

I want to set the criteria about this item.

Can I set this item?

What does this have to do with MATLAB?

Maybe the question is of Polyspace Bug Finder?

Yep. :)

In general, it is not expected that every Bug Finder result must be fixed. My recommendation would be to review the defect using a status such as "No Action Planned" and add a comment to the effect that "13 bytes is not worth optimizing to pass by reference unless we encounter performance issues later when calling this function".

I believe there is not currently a way to set a minimum byte threshold (e.g. 16 bytes) for the expensive pass by value checker.
