Initialize state dependent part of calculation.

From a state vector

Implements BIE::Model.

Member Data Documentation

double BIE::PopModelND::ALPHA [static]

Jacobi quadrature parameters (default: 0, 0).

NB: For real $x$ the Jacobi polynomial is:

$P_n^{(\alpha,\beta)}(x)= \sum_s {n+\alpha\choose s}{n+\beta \choose n-s} \left(\frac{x-1}{2}\right)^{n-s} \left(\frac{x+1}{2}\right)^{s}$

The Jacobi polynomials satisfy the orthongonality relationship:

$\int_{-1}^1 (1-x)^{\alpha} (1+x)^{\beta} P_m^{(\alpha,\beta)} (x)P_n^{(\alpha,\beta)} (x) \; dx= \frac{2^{\alpha+\beta+1}}{2n+\alpha+\beta+1} \frac{\Gamma(n+\alpha+1)\Gamma(n+\beta+1)}{\Gamma(n+\alpha+\beta+1)n!} \delta_{nm}$

where $\alpha>-1$ and $\beta>-1$ . Alpha index value
