slegendre.inner.products: Inner products of shifted Legendre polynomials
Description
This function returns a vector with \(n + 1\) elements containing the inner product of
an order \(k\) shifted Legendre polynomial, \(P_k^* \left( x \right)\),
with itself (i.e. the norm squared) for orders \(k = 0,\;1,\; \ldots ,\;n \).
Usage
slegendre.inner.products(n)
Arguments
n
integer value for the highest polynomial order
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 inner products is as follows.
