#include <vigra/polynomial.hxx>
Namespace: vigra
| Polynomial | ( | unsigned int | order = 0, |
| double | epsilon = 1.0e-14 |
||
| ) |
Construct polynomial with given order and all coefficients set to zero (they can be set later using operator[] or the iterators). epsilon (default: 1.0e-14) determines the precision of subsequent algorithms (especially root finding) performed on the polynomial.
| Polynomial | ( | Polynomial< T > const & | p | ) |
Copy constructor
| Polynomial | ( | ITER | i, |
| unsigned int | order | ||
| ) |
Construct polynomial by copying the given coefficient sequence.
| Polynomial | ( | ITER | i, |
| unsigned int | order, | ||
| double | epsilon | ||
| ) |
Construct polynomial by copying the given coefficient sequence. Set epsilon (default: 1.0e-14) as the precision of subsequent algorithms (especially root finding) performed on the polynomial.
| Polynomial& operator= | ( | Polynomial< T > const & | p | ) |
Assigment
| Polynomial<T> getDerivative | ( | unsigned int | n = 1 | ) | const |
Construct new polynomial representing the derivative of this polynomial.
| Polynomial<T> getDeflated | ( | Real | r | ) | const |
Construct new polynomial representing this polynomial after deflation at the real root r.
| Polynomial<Complex> getDeflated | ( | Complex const & | r | ) | const |
Construct new polynomial representing this polynomial after deflation at the complex root r. The resulting polynomial will have complex coefficients, even if this polynomial had real ones.
