New Insights in Exponentially-Fitted Methods

5 New Insights in Exponentially-Fitted Methods. - In the last two years (1998 and 1999) the following new insights in the subject have been developed. Simos and Williams26 have presented computer algebra programs in Maple 

Simos27,28 has derived explicit four-step sixth algebraic order almost P-stable exponentially-fitted methods of the form  

Simos29 has derived a family of explicit almost P-stable fourth algebraic order two-step methods of the form
