Hello,
I am trying to use the ode15i function. This needs the sundials library. On configuring with options to point to sundials libraries, I get the following warning:
configure: WARNING: KLU library not found. This will result in some lack of functionality for sparse matrices.
configure: WARNING: SUNDIALS IDA library does not include the IDADENSE linear solver, ode15i and ode15s will be disabled
configure: WARNING: SUNDIALS IDA library not configured with IDAKLU, ode15i and ode15s will not support the sparse Jacobian feature
I have looked around online for a resolution to this issue and have not found a usable solution. I am getting sundials by cloning from their git repository, and am configuring with the octave-5.2.0 configure script.
