* Function : IDASpgmr
* -----------------------------------------------------------------
* A call to the IDASpgmr function links the main integrator with
* the IDASPGMR linear solver module. Its parameters are as
* follows:
*
* IDA_mem is the pointer to memory block returned by IDACreate.
*
* maxl is the maximum Krylov subspace dimension, an
* optional input. Pass 0 to use the default value,
* MIN(Neq, 5). Otherwise pass a positive integer.
*
* The return values of IDASpgmr are:
* IDASPILS_SUCCESS if successful
* IDASPILS_MEM_NULL if the IDAS memory was NULL
* IDASPILS_MEM_FAIL if there was a memory allocation failure
* IDASPILS_ILL_INPUT if there was illegal input.
* The above constants are defined in idas_spils.h
