Get computer name/hostname

It provides the computer name where running. Useful for customizing scripts depending on the machine

Description

GETCOMPUTERNAME is a very simple but useful function to get your computer name, i.e. the hostname.

Example:

> mycomputer = getComputerName();

• MATLAB release: MATLAB 7.1.0 (R14SP3)

Manuel, you can't publish something as trivial as this:

[ret, name] = system('hostname');

if ret ~= 0,
   if ispc
      name = getenv('COMPUTERNAME');
   else
      name = getenv('HOSTNAME');
   end
end
name = lower(name);

I don't see how you can improve this because it is very trivial.

My suggestion is to delete it...

Thanks for your comment but, from my point of view, if I have to rewrite 10 lines of code hundreds of times, independently of the difficulty, it worths to pack them into a function.

This (indeed trivial) function will produce a misleading error ('Undefined function or variable "name".') if "ret", for whatever reason, equals zero. If ret is always non-zero, why check? And why convert it to lower case?

The help could be improved, by adding a H1, SEE ALSO lines.

If ret ~= 0, it means that command 'hostname' has not been found in the system. So, an alternative way, based on enviromental variables, is tried. On the other hand, 'name' always is set to a value, either by system() or by getenv.

THANKS FOR THE CODE

[Alex Leung]

Absolutely no problem at all!

[Cesare]

I think it was usefull. I didn't know how to do it, now I do.

[Richard Crozier]

Marcelo and Jos, I for one find this a really useful function which saved my looking up the obscure (to me) functions used within it. This has saved me probably at least an hour of searching through help. So basically you can get lost.

Manuel do not delete the file, it's helped me, thank you!
