| Abstract: | This paper presents the Pad\'{e}-type approximation for pseudo-multivariate functions. This approximation can simplify the calculation of the multivariate rational approximation, and accelerate the convergence of the function at the singular point. The properties and error analysis of the Pad\'{e}-type approximation for pseudo-multivariate functions are given. |

| Keywords: | Pseudo-multivariate functions Pad\'{e} approximation Pad\'{e}-type approximation error analysis |
