A Boolean value indicating whether the polynomial defined by
qspray
is homogeneous. Moreover, if it is homogeneous, the degree
is given in the attribute "degree"
of the output.
Examples
lambda <- c(3, 2, 1)
p <- PSFpoly(4, lambda)
( homogeneous <- isHomogeneousQspray(p) ) # should be TRUE
attr(homogeneous, "degree") == sum(lambda) # should be TRUE
