<p dir="auto">A quick and easy way to get ode23 and ode45 like in MATLAB is:</p>

<p dir="auto">The state of the art is SUNDIALS, but it is no longer maintained. The lead developer went to develop video games! It is widely used in the national labs, and can give us ode15s.</p>

<p dir="auto">The long term strategy may simply be to implement these solvers in julia itself. The design of the Matlab ODE suite is described in:</p>

<p dir="auto">I realize this is probably due to a compilation error or system modifications; or some such.<br>
I can't find a reference to Ulong failures in google though.<br>
A pointer to relevant documentation, system/compiler dumps, would be appreciated.  I realize that<br>
Mint, 64 bit, AMD<br>
is not a through description but I don't want to clutter up the board with useless information.<br>
I do know (more or less) how to do strace and such if needed.<br>
