Matlab: generate unique ID number
To generate a unique ID number for e.g. a temporary file or seed for random number generator current date/time in milliseconds can be used. I matlab the only command that gives time in milliseconds is datestr with FFF input e.g. datestr(now,'MMSSFFF')
ans =
5139451 datestr(now,'MMSSFFF')
ans =
5140057
UID=datestr(now,'MMSSFFF')
UID =
5214981
Unfortunatly other commands such as cputime or now don't return time in milliseconds, which is not so good.
Howdy! Someone in my Facebook group shared this website with us so I came to give it a look. I'm definitely enjoying the information. I'm bookmarking and will be tweeting this to my followers! Terrific blog and brilliant design.
I know this if off topic but I'm looking into starting my own blog and was wondering what all is required to get set up? I'm assuming having a blog like yours would cost a pretty penny? I'm not very web savvy so I'm not 100% sure. Any recommendations or advice would be greatly appreciated. Thank you
