Well, if csv fits your needs....
I had a brief look at dlmwrite and csvwrite; I conclude that Bill Krekeler's
suggestion to write a custom csvwrite (/csvread) may be the easiest way to
go for mixed float/string I/O in .csv format.
One of these days I'll have a look at it, but first: taxes! (< April 1st) -
so don't hold your breath...

No, this won't help; if the POI interface were be supported on Jonathan's
PC, xlsopen.m (invoked by xlswrite) would have detected it already and fall
back to it.
But it says "NONE" - the default placeholder interface name before any
interface check has been done, implying no support at all could be detected.
I suppose a Java JRE is lacking as well.
Did you try "java -version" in a Command prompt?

Perhaps .... I vaguely remember reading something like that on the Mathworks
site or in comp.soft-sys.matlab, but I cannot find it now. I have no
MS-Office 2007 so I couldn't test it myself, but here's the very first
report about failure although the Excel support scripts for Octave exist for
over a year.
POI is Java-based, be sure to have at least a Java JRE installed - get one
here:

Again I strongly suggest to follow the troubleshooting guide I mentioned in
another post, step by step.
That'll show exactly where things go wrong.
