If you have found your pvengine.exe you can wrap the
pov call in a script file, like the one below.
(I think I am not allowed to use an attachment here,
so I split a couple of the lines to fit in a
reasonable width).

You can call this function as:
povray(filename)
or with name-value pairs
povray(filename,'Width',320,'Height',240,'Options','+V')

you can use any number of name-value pairs. I have defined
only three, but you can easily add your own.

Note: this assumes that you have set your inifile in povray
and that you have selected
'Render/On Completion .../Exit POV-Ray for Windows'
from the menu.
There must be a way to specify the inifile you want to use
and that you want to exit after completion from the command
line, but I can not find how.

Actually, your mail prompted me to investigate some more.
After writing the above I found that I can specify the
inifile. There are still a number of problems however,
so I can not give a working version of the matlabscript
that includes the inifile yet.
- You have to specify the complete path for the inifile
- The commandline parser does not parse quotes. You can
  therefore not use a long filename that includes spaces
  and put "" around them. In fact you have to use the
  DOSfilename. In my case "c:\progra~1\pov-ra~1.5\" etc
- it still complains that "never found section '' in file..."
  This is where I give up :(
