Eigenvalue & eigenvectors Problems

[metalasia]

hi,
i intend to develop from scratch the Eigenvalue & eigenvectors programs (c/c++)
using QR Iteration or Robust Representation (RRR).

anyone have good source/tutorial about both algorithm (QR Iteration or RRR) especially in computational aspects.

thanx

IMHO you can't easily beat Jacobi's method for matrices <128x128. Computers are very good at simple repeditive calculations and Jacobi's method is very robust if a little slow in converging.

i already have source the eigenvalue & eigenvectors using Jacobi method ....


now, i need good numerical/computational theory about QR Iteration or
RRR coz i intend to develop c/c++ programme.

thanx
