In this research, we suggest Product-type of Iterative method with Approach run which gives shadow residual of BiCG method iterated for some steps to initial shadow residual of producttype of iterative method, and show the validity through some numerical experiments.}, title = {BiCG法による助走区間つき積型反復法の収束性評価}, year = {2008} }
