[petsc-users] Use kspsolve repeatly

[丁老师]

I need to use the kspsolve(A,b,x) repeatly in my code in the following style.
but i have noticed from the system load monitor that during the code running, 
it allocate new memeory every step.


I use the default setting for the PC. 
Could you please told me how to resolve this problem.






for (int i=0;i<maxit;i++)
{
MatsetValues(    )....
kspsolve(A,b,x)
}
