nvec

The number of orthogonal vectors the operation maintains.

Declaration

var nvec: Int32

Discussion

For GMRES and FGMRES variants, this is the number of iterations between restarts. For DQGMRES it’s the number of historical vectors the operation maintains in memory. If nvec is less than or equal to 0, the operation uses the default value of 16.
