SylvesterMatrix class

A Sylvester matrix is used to compute the discriminant of a polynomial starting from its coefficients.

Constructors

SylvesterMatrix({required List<Complex> coefficients})

The constructor requires complex coefficients for the polynomial P(x).

SylvesterMatrix.fromReal({required List<double> coefficients})

The constructor requires real coefficients for the polynomial P(x).

Properties

coefficients → List<Complex>

The coefficients of the polynomial from which the Sylvester matrix will be built. The list is unmodifiable.
