good morning
I read the article titled 'SINRD Circuits Analysis with WCIP' we can solve the equation system (10) by the GMRES algorithm
So to use the GMRES we must put the system in the form of equation (11) something I've already done that is to say the system is like this we have: A*x = b
my question is how can we write equation (11) in matlab to use the GMRES
thank you
I didn't read the paper, only the equation (11). If the part in parenthesis represents a matrix and if Az is the unknown, you should be able to represent this equation in matlab.
Dear Zed Bib, I've never used GMRES before. Nevertheless, the BiCGStab or BiCGStab(2) may be very useful for you. On the other hand, the own Matlab built-in functions should be sufficient to solve your problem. I suggest you to read about these methods or try using some another one.
Best wishes and good luck with your research!
Dear Zed Bib,
GMRES in matlab has pretty much the same calling sequence as CG, except the restarting parameter. The main arguments are the matriox, the right-hand side vector and the solution vector, plus the tolerance. For good convergence you will need a good preconditioner. Try ILU(0), if it does not work, you may want to use algebraic multigrid, which is known to behave well for circuit equations..
