hermite.h.inner.products {orthopolynom} | R Documentation |
This function returns a vector with n + 1 elements containing the inner product of an order k Hermite polynomial, H_k ≤ft( x \right), with itself (i.e. the norm squared) for orders k = 0,\;1,\; … ,\;n .

integer value for highest polynomial order |
The formula used to compute the innner product is as follows.
h_n = ≤ft\langle {H_n |H_n } \right\rangle = √ π \;2^n \;n!.
A vector with n + 1 elements
