jacobi.p.inner.products: Inner products of Jacobi polynomials
Description
This function returns a vector with \(n + 1\) elements containing the inner product of
an order \(k\) Jacobi polynomial, \(P_k^{\left( {\alpha ,\beta } \right)} \left( x \right)\),
with itself (i.e. the norm squared) for orders \(k = 0,\;1,\; \ldots ,\;n \).
Usage
jacobi.p.inner.products(n,alpha,beta)
Arguments
n
integer value for the highest polynomial order
alpha
numeric value for the first polynomial parameter
beta
numeric value for the first polynomial parameter
Value
A vector with \(n + 1\) elements
1
inner product of order 0 orthogonal polynomial
2
inner product of order 1 orthogonal polynomial
...
n+1
inner product of order \(n\) orthogonal polynomial
Details
The formula used to compute the innser products is as follows.
