DSNEPMatrixFunctionFn#
A prototype of a DSNEP compute matrix function that would be passed to DSNEPSetComputeMatrixFunction()
Synopsis#
PETSC_EXTERN_TYPEDEF typedef PetscErrorCode DSNEPMatrixFunctionFn(DS ds,PetscScalar lambda,PetscBool deriv,DSMatType mat,void *ctx);
Calling Sequence#
ds - the direct solver object
lambda - point where T(lambda) or T’(lambda) must be evaluated
deriv - if true compute T’(lambda), otherwise compute T(lambda)
mat - the DS matrix where the result must be stored
ctx - [optional] user-defined context for private data for the matrix evaluation routine (may be
NULL
)
