Hello all, I am new to this forum but am glad I found it, I have a quick question about condition numbers and order of operations. Given a symmetric positive-definitive matrix with a initial condition number α, is it possible to improve that condition number with a different access pattern? For example, if I access the matrix within the context of an iterative solver (e.g., Jacobin) in column-major order would it improve the condition number over access done in row-major order? I am doing some personal research into iterative solvers and convergence rates and I would like to know if the condition number can be improved, thus lower the total number of iterations to converge, significantly with something so small. Thank you.
