ode45 for simultaneous equations?

[Charles Coronella]

I'm trying to utilize ode45 to solve multiple simultaneous ODEs. I have no
problems using ODE45 for a single ODE, but I can't seem to get it to
function properly for multiple ODEs.

To make sure I'm not screwing up the syntax, I copied the syntax from
Mathsoft:
http://www.mathworks.com/access/helpdesk/help/techdoc/index.html?/access/helpdesk/help/techdoc/ref/ode23.html
Example 1 has three simultaneous equations.

Am I doing something stupid? Do others use ose45 for this purpose?

The error I get back says:
error: operator \: nonconformant arguments (op1 is 2x2, op2 is 1x2)
error: evaluating binary operator `\' near line 317, column 23
error: evaluating assignment expression near line 317, column 15
error: evaluating for command near line 304, column 5
error: evaluating while command near line 297, column 3
error: called from `ode45' in file `d:\Octave\share\octave\packages\odepkg-
0.3.3\ode45.m'
error: near line 5 of file `C:\Documents and Settings\ccoronella\My
Documents\Octave\driver.m'


Thanks.
