The concept of partial Padé approximation, introduced by Claude Brezinski, is generalized to the case of simultaneous rational approximation with common denominator. The use of information about known poles and/or zeros, can lead to approximants with a better numerical behaviour than in the case of ordinary simultaneous Padé approximation.
