Octave v7.3.0 Windows problem with ode45 function

[fletchjp]

I have installed Octave 7.3.0 on Windows 11. I have also installed Anaconda and Jupyter to run Octave. I have old examples which use the function ode45. In older versions of Octave this was in odepkg which is no longer supported. An example runs with Octave but fails with Jupyter saying that I need to install odepkg.

I have run jupyter console -kernel octave which reports Jupyter console 6.4.3, Octave kernel v0.35.1 and Octave v7.3.0

The error message is:
error: pkg odepkg is not installed
error: called from load packages at line 47 column 7, pkg at line 632 column 7

I do not know what file is being referred to here.

On my setup the code for ode45 is located here:

C:\Program Files\GNU Octave\Octave-7.3.0\mingw64\share\octave\7.3.0\m\ode\ode45.m

I hope I have given enough information to find the problem.
