A general definition of multivariate Padé approximants is given which includes previous definitions of several authors as special cases. The coefficients of the polynomials in the numerator and the denominator of the Padé approximant are determined by a system of linear equations. A representation in terms of determinants is given. By considering suitable intermediate approximation problems, the multivariate Padé approximant can be calculated by a recursive algorithm.
