** If yes, what task did you choose? Please describe what part of it you especially want to focus on if you can already provide this information.

I choose the project "[http://wiki.octave.org/Summer_of_Code_Project_Ideas#Improve_iterative_methods_for_sparse_linear_systems Improve iterative methods for sparse linear systems]". It is not a new project. Cristiano Dorigo did part of it in SOCIS2016. He improved pcg, gmres, bicg, bicgstab and cgs, and added tfqmr. The two functions pcr and qmr still need to be improved, and four functions minres, symmlq, bicgstabl and lsqr need to be added. I will mainly focus on adding the new functions, while at the same time I will test Cristiano Dorigo's work and improve all the functions like the way he did.

** Learning more about the organization’s community, read the references and test Cristiano Dorigo's code.
