摘要
In this paper, a new matrix pade approximants which is based on generalized inverse is obtained. It is different from original matrix pade approximants in that it need not use multiplication of matrixces in its constructive process, hence, lefthanded pade approximants is same as right-handed ones in the cases. Generalized inverse matrix pade approximants can be computed by two methods: (i) the determinantal formula for denoninator polynomials; (ii) matrix -algorithm. The results in the paper are verified by some numerical examples.
