hostname.m

Report the name of computer on which Matlab is currently running.

Description

This function reports the name of computer on which Matlab is currently running, and works under multiple operating systems.

• MATLAB release: MATLAB 7.8 (R2009a)

Despite the claim, this fails to run on all operating systems. Try it on a PPC Mac. No go.

unix('hostname') works fairly well if you are on a PPC mac. I've not verified it is correct for an intel mac.

[Thierry Dalon]

(For windows only?)
Be aware: the call to unix('hostname') or system('hostname') gives you an empty sign a the end. You need to DEBLANK it!

See example:
[status,name]= unix('hostname')

status =

     0

name =

RBGD0SGC

>> length(name)

ans =

     9

That is to my opinion the only benefit for such an easy wrapper function else.

[John D'Errico]

Macs will return either of MACI or MAC, depending upon whether the system is an older or new inter Mac system. The help for computer.m states this fact.

So hostname still fails to work on older MAC systems, although it will probably now run on intel based macs.

Also, this submission too has the flaw that it has a blank comment line BEFORE what serves as an H1 line. Since that disables lookfor, it is a flaw, and a silly one. I'm not at all sure why the author insists on doing this. It is unfriendly to disable a very useful feature of MATLAB for absolutely no good reason.

use of java system calls is (likely) a more os independent way to retrieve such information, eg,
