How to do parallel bicg(or bicgstab) on distributed arrays?

Hi, I am trying to solve a linear system using iterative methods such as bicg or bicgstab.

The target matrix to be solved is quite large, e.g., the number of non-zeros would be larger than 1 billion. Hence, It would be good if I can put the target matrix into a distributed array, and solve the distributed array in parallel.

Is it possible to solve the linear system on distributed arrays using bicg supported by MATLAB? Or, do I need to use other third part libraries such as PETSC?

Hi Jinhong,

To see an example of using bicg with distributed arrays please open your version of MATLAB and type

>> doc distributed/bicg

in the MATLAB Command Window.

Thanks for answering my question, but there is no result for "doc distributed/bicg". My MATLAB version is R2015b.
