[Octave-bug-tracker] [bug #55905] ode15{i, s} allocate enough memory for a full jacobian when the provided jacobian is sparse

[Bill Greene]

Follow-up Comment #1, bug #55905 (project octave):

I fixed this bug following the suggestion in the
"FIXME comment". An hg patch file is attached.
Note, one implication of this fix is that SUNDIALS 4 (or greater)
is now required because the function, SUNSparseMatrix_Reallocate,
used in the fix is not available in older versions of SUNDIALS.
