MFNSolveTranspose#

Solves the transpose matrix function problem. Given a vector \(b\), the vector \(x = f(A^T)b\) is returned.

Synopsis#

#include "slepcmfn.h" 
PetscErrorCode MFNSolveTranspose(MFN mfn,Vec b,Vec x)

Collective

Input Parameters#

  • mfn - the matrix function solver context

  • b - the right hand side vector

Output Parameter#

  • x - the solution (this may be the same vector as b, then b will be overwritten with the answer)

Notes#

The matrix \(A\) is specified with MFNSetOperator(). The function \(f\) is specified via the FN object obtained with MFNGetFN() or set with MFNSetFN().

See available command-line options at MFNSolve().

Developer Notes#

This is currently implemented with an explicit transpose matrix created with MatCreateTranspose().

Currently there is no conjugate-transpose version.
