Detailed Description

Determination of Zolotarev coefficients.

This class determines the Zolotarev's optimal coefficients of partial fractional approximation to 1/sqrt(x). Present implementation makes use of the code in Numerical Recipes, and thus cannot be put public. To be replaced with public implementation. [28 Dec 2011 H.Matsufuru]
