Polyroots calculator software#

To enter a polynomial you just type 'naturally' E.g. The polynomial is generally written on the form a nx n+a n-1x n-1.a 1x+a 0 where a is a real or complex number and n is an integer. Of any degree with either real or complex coefficients. This Polynomial solver finds the real or complex roots of a polynomial Notice that all methods are so-called modified methods, which maintain their convergence rate even for multiple roots. See the Authors paper on the subject Read more. However, I have recently added other methods: Ostrowski, Halley's, Householder 3 rd order, Jenkins-Traub, Laguerre's, Eigenvalue, Durand-Kerner, Aberth-Ehrlich, Chebyshev & Ostrowski Square root method. The method was originally based on a modified Newton iteration method developed by Kaj Madsen back in the seventies, see. This Polynomial solver finds the real or complex roots (or zeros) of a polynomial OF LIABILITY, ARISING OUT OF OR IN CONNECTION WITH THE USE OR PERFORMANCE OF THIS SOFTWARE.
