✦ Synopsis


We study (Sections 1 and 2) the speed of convergence of the q-d algorithm to poles of a meromorphic function in order to accelerate it.

In Section 3 and 4, we show that the quotient of two successive vertical terms of two well known algorithms (r-s and c) approaches also these poles. At last, a theorem of acceleration is given.
