PetscErrorCode LMESolve(LME lme)

Collective

Input Parameter#

  • lme - the linear matrix equation solver context

Options Database Keys#

  • -lme_view - print information about the solver once the solve is complete

  • -lme_view_pre - print information about the solver before the solve starts

  • -lme_view_mat_a - view the A matrix

  • -lme_view_mat_b - view the B matrix

  • -lme_view_mat_d - view the D matrix

  • -lme_view_mat_e - view the E matrix

  • -lme_view_rhs - view the right hand side of the equation

  • -lme_view_solution - view the computed solution

  • -lme_converged_reason - print reason for convergence/divergence, and number of iterations

Notes#

The matrix coefficients are specified with LMESetCoefficients(). The right-hand side is specified with LMESetRHS(). The placeholder for the solution is specified with LMESetSolution().

All the command-line options listed above admit an optional argument specifying the viewer type and options. For instance, use -lme_view_mat_a binary:amatrix.bin to save the \(A\) matrix to a binary file.
