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`)
