SLESSetUp

Performs set up required for solving a linear system.

Synopsis

int SLESSetUp(SLES sles,Vec b,Vec x)

Input Parameters

sles -the SLES context
b -the right hand side
x -location to hold solution

Collective on SLES

Note

For basic use of the SLES solvers the user need not explicitly callSLESSetUp(), since these actions will automatically occur duringthe call to SLESSolve(). However, if one wishes to generateperformance data for this computational phase (for example, forincomplete factorization using the ILU preconditioner) using thePETSc log facilities, calling SLESSetUp() is required.

Keywords

SLES, solve, linear system
