Inner products of Laguerre polynomials
Description
This function returns a vector with n + 1 elements containing the inner product of
an order k Laguerre polynomial, L_n \left( x \right),
with itself (i.e. the norm squared) for orders k = 0,\;1,\; \ldots ,\;n .
Usage
laguerre.inner.products(n)
Arguments
n |
integer value for the highest polynomial order |
Details
The formula used to compute the inner products is as follows.
h_n = \left\langle {L_n |L_n } \right\rangle = 1.
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 |
