NEPSetTarget#
Sets the value of the target.
Synopsis#

PetscErrorCode NEPSetTarget(NEP nep,PetscScalar target)
Logically Collective
Input Parameters#
nep - the nonlinear eigensolver context
target - the value of the target
Options Database Key#
-nep_target <target> - the value of the target
Notes#
The target is a scalar value used to determine the portion of the spectrum
of interest. It is used in combination with NEPSetWhichEigenpairs().
When PETSc is built with real scalars, it is not possible to specify a complex target.
In the case of complex scalars, a complex value can be provided in the
command line with [+/-][realnumber][+/-]realnumberi with no spaces, e.g.
-nep_target 1.0+2.0i.
