Hi,<br>
<br>
I have a complex system of equations and I use PETSc to solve the<br>
system. I also use MKL to create the preconditioner using ILU. The ILU<br>
preconditioner is created only on the real part of the coefficient<br>
matrix and is stored in CSR format with the data type of double<br>
precision. I wanted to ask if it is possible to use this preconditioner<br>
and pass it to PETSc in CSR format? Can it be used with PETSc complex<br>
solver although the preconditioner is in double precision format?<br>
<br>
Regards,<br>
