Find the Roots of a Polynomial Given its Coefficients
polyrt(coeffs,m=100,eps=1.e-6)
coeffs |
Array of length $p+1$ containing the coefficients of the
polynomial of degree $p$, ({coeffs }(i) is the coefficient of power
$i-1$). |
m |
Integer containing the maximum number of iterations in the procedure. |
eps |
Real scalar indicating the convergence criterion. |
polyrt |
returns a list containing the following items: |
real |
Array of length $p$ containing the real parts of the roots. |
imag |
Array of length $p$ containing the imaginary parts of the roots. |
ier |
Integer variable indicating whether or not the procedure converged (0 means yes, 1 means no). |
