SLESSetUp
Performs set up required for solving a linear system.
Synopsis
int SLESSetUp(SLES sles,Vec b,Vec x)
Collective on SLES
Input Parameters
sles | - the SLES context
|
b | - the right hand side
|
x | - location to hold solution
|
Note
For basic use of the SLES solvers the user need not explicitly call
SLESSetUp(), since these actions will automatically occur during
the call to SLESSolve(). However, if one wishes to generate
performance data for this computational phase (for example, for
incomplete factorization using the ILU preconditioner) using the
PETSc log facilities, calling SLESSetUp() is required.
Keywords
SLES, solve, linear system
