Inner products of ultraspherical polynomials
Description
This function returns a vector with n + 1 elements containing the inner product of
an order k ultraspherical polynomial, C_k^{\left( \alpha \right)} \left( x \right),
with itself (i.e. the norm squared) for orders k = 0,\;1,\; \ldots ,\;n .
Usage
ultraspherical.inner.products(n,alpha)
Arguments
n |
integer value for the highest polynomial order |
alpha |
numeric value for the polynomial parameter |
Details
This function uses the same formula as the function gegenbauer.inner.products.
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 |
