Hi,

is there a possibility to use the routines dcsrilu0 or dcsrilut on complex sparse matrices?

Thank you!

Stefan

Hi Stefan,

Thank you for using Intel MKL!

Current implementation of preconditioners does not allow straightforward usage for complex matrices. You may use one of 2 options available.

First option would be to file feature request for complex preconditioners through http://premier.intel.com site (registration is required).

Second option is to convert the complex system to real one (twice larger with separatedreal and imaginary parts) andapply preconditionerstothis real system.

Kind regards,

Sergey G
