Polynomial with internally managed array of static length.
Most interesting functionality is inherited from vigra::PolynomialView. This class differs from vigra::Polynomial in that it allocates its memory statically which is much faster. Therefore, StaticPolynomial
can only represent polynomials up to the given MAXORDER
.

StaticPolynomial | ( | unsigned int | order = 0 , |
double | epsilon = 1.0e-14 |
||
) |
Construct polynomial with given order <= MAXORDER
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.
StaticPolynomial | ( | StaticPolynomial< MAXORDER, T > const & | p | ) |
Copy constructor
StaticPolynomial | ( | ITER | i, |
unsigned int | order | ||
) |
Construct polynomial by copying the given coefficient sequence. order <= MAXORDER
is required.
StaticPolynomial | ( | ITER | i, |
unsigned int | order, | ||
double | epsilon | ||
) |
Construct polynomial by copying the given coefficient sequence. order <= MAXORDER
is required. Set epsilon
(default: 1.0e-14) as the precision of subsequent algorithms (especially root finding) performed on the polynomial.
StaticPolynomial & operator= | ( | StaticPolynomial< MAXORDER, T > const & | p | ) |
Assigment.
StaticPolynomial getDerivative | ( | unsigned int | n = 1 | ) | const |
Construct new polynomial representing the derivative of this polynomial.
StaticPolynomial getDeflated | ( | Real | r | ) | const |
Construct new polynomial representing this polynomial after deflation at the real root r
.
StaticPolynomial< MAXORDER, 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.
