Member Function Documentation

template<typename Scalar , typename ArrayScalar >
static int Intrepid::TabulatorTet< Scalar, ArrayScalar, 0 >::idx ( int  p,
int  q,
int  r 
) [inline, static]

function for indexing from orthogonal expansion indices into linear space p+q+r = the degree of the polynomial.

Parameters:
p[in] - the first index
q[in] - the second index
r[in] - the third index

template<typename Scalar , typename ArrayScalar >
static void Intrepid::TabulatorTet< Scalar, ArrayScalar, 0 >::jrc ( const Scalar &  alpha,
const Scalar &  beta,
const int &  n,
Scalar &  an,
Scalar &  bn,
Scalar &  cn 
) [inline, static]

function for computing the Jacobi recurrence coefficients so that

Parameters:
alpha[in] - the first Jacobi weight
beta[in] - the second Jacobi weight
n[n] - the polynomial degree
an[out] - the a weight for recurrence
bn[out] - the b weight for recurrence
cn[out] - the c weight for recurrence

The recurrence is

\[ P^{\alpha,\beta}_{n+1} = \left( a_n + b_n x\right) P^{\alpha,\beta}_n - c_n P^{\alpha,\beta}_{n-1} \]

, where

\[ P^{\alpha,\beta}_0 = 1 \]

template<class Scalar , class ArrayScalar >
void Intrepid::TabulatorTet< Scalar, ArrayScalar, 0 >::tabulate ( ArrayScalar &  outputValues,
const int  deg,
const ArrayScalar &  inputPoints 
) [static]

basic tabulate mathod evaluates the basis functions at inputPoints into outputValues.

Parameters:
[out]outputValues- rank 2 array (F,P) holding the basis functions at points.
[in]deg- the degree up to which to tabulate the bases
[in]inputPoints- a rank 2 array containing the points at which to evaluate the basis functions.
