Hi All,
In my work I would like to solve a thousands of moderate size systems of linear equations, parallelly. The uniquum in my problem is that, I am not interested in the whole solutions of the systems, but only several elements of the solution vectors are interesting.
To be more strict:
Let a set of system of linear equations be given:
A(i)⋅x(i)=y(i), i=1..N,
All the matrices A(i) and vectors y(i) are real.
The dimensions of the systems are equal and it is typical between 10 and 39.
The number of systems is typical N>5000.
The problem for example is to determine the x(i)1, x(i)3,
x(i)4 for all i=1..N.
The question: Have you ever heard any similar selective solver for linear equations? Direct and itterative solvers are also interesting for me.
Thank you for your help in advance!
