✦ Synopsis

A method is presented for determination of an n th order rational transform approximation for a time function, given at least n + 1 of its Laguerre coefficients. The method is based on approximating the discrete set of Laguerre coefficients with a rational generating function. The method does not require predetermination of the poles; and allows the use of as many Laguerre coefficients as are available, without increasing the complexity of the model. Applications to time domain synthesis and transfer function identification are discussed.

The Levin u-transform is used as a method of summation of the divergent perturbation series expansion for the conformation factor in the excluded-volume problem of dilute polymer solutions. The rational approximants thereby generated are superior to Pad6 approximants regarding their consistency with
