* Function : IDABand
* -----------------------------------------------------------------
* A call to the IDABand function links the main integrator
* with the IDABAND linear solver module.
*
* ida_mem is the pointer to the integrator memory returned by
* IDACreate.
*
* mupper is the upper bandwidth of the banded Jacobian matrix.
*
* mlower is the lower bandwidth of the banded Jacobian matrix.
*
* The return values of IDABand are:
* IDADLS_SUCCESS = 0 if successful
* IDADLS_LMEM_FAIL = -1 if there was a memory allocation failure
* IDADLS_ILL_INPUT = -2 if the input was illegal or NVECTOR bad.
*
* NOTE: The band linear solver assumes a serial implementation
* of the NVECTOR package. Therefore, IDABand will first
* test for a compatible N_Vector internal representation
* by checking that the N_VGetArrayPointer function exists.
