construct.P {SSM} | R Documentation |
Construct the change of basis matrix from multivariate monomials to Legendre polynomials.
Description
Let f(x)
be the vector of monomials implied by the matrix basis
.
Let P
be the matrix generated by Legendre_P
. Then
g(x)=P^Tf(x)
is the vector of Legendre polynomials with leading terms
corresponding to basis
.
Usage
construct.P(basis)
Arguments
basis |
A matrix. Rows are taken as the degree of the associated monomial. |
Value
A matrix which functions as a change of basis from monomials to Legendre.
