copy

问题 This question has been bothering me for some time. The possibilities I am considering are memcpy std::copy cblas_dcopy Does anyone have any clue on what the pros and cons are with these three?

I want to build in an update function, so that when I open the file, the version in the file will check against my local version, and if my local version is a higher version number, it will update to my script.
