Legendre polynomials of arbitrary degree. Constructing a Legendre polynomial of degree p
, the coefficients will be computed by the three-term recursion formula.

Polynomials::Legendre::Legendre | ( | const unsigned int | p | ) |
Constructor for polynomial of degree p
.
|
static |
Return a vector of Legendre polynomial objects of degrees zero through degree
, which then spans the full space of polynomials up to the given degree. This function may be used to initialize the TensorProductPolynomials and PolynomialSpace classes.
|
staticprivate |
Compute coefficients recursively. The coefficients are stored in a static data vector to be available when needed next time. Since the recursion is performed for the interval , the polynomials are shifted to
by the
scale
and shift
functions of Polynomial
, afterwards.
|
staticprivate |
Get coefficients for constructor. This way, it can use the non-standard constructor of Polynomial.

Coefficients for the interval .

Vector with already computed coefficients. For each degree of the polynomial, we keep one pointer to the list of coefficients; we do so rather than keeping a vector of vectors in order to simplify programming multithread-safe. In order to avoid memory leak, we use a shared_ptr in order to correctly free the memory of the vectors when the global destructor is called.
