roots(x, method = c("polyroot", "eigen"))x |
Polynomial coefficients with coefficients given in order from highest to lowest
polynomial power. This is the Matlab/Octave convention; it is
opposite of the convention used by |
method |
Either “polyroot” (default) which uses |
A complex array with the roots of the polynomial.
