The goal of this library is to construct polynomial and rational approximations given a collection of point data consisting of pairs of inputs and outputs that minimizes (for example) The ultimate ...

Abstract: A new algorithm for performing the arbitrary polynomial transformation for single and multiple variables is presented. It is based on the polynomial interpolation of the numerator and the ...

Abstract: This brief presents a necessary and sufficient condition for testing positive, real, imaginary, and negative rational functions. A related term, the positive, imaginary, and negative ...
