Calculate the p-norm of any function between given limits.
generalPNorm(fun, p, lower, upper, range = NULL)
fun |
function to calculate the p-norm of. |
p |
the pth norm to calculate |
lower |
lower bound for the integral |
upper |
upper bound for the integral |
range |
if discrete then range of the function to sum over |
The p-norm of a continuous function f
is given by,
(\int_S |f|^p d\mu)^{1/p}
where S
is the function support. And for a discrete function by
\sum_i (x_{i + 1} - x_i) * |f(x_i)|^p
where i
is over a given range.
The p-norm is calculated numerically using the integrate
function and therefore results
are approximate only.
Returns a numeric value for the p norm of a function evaluated between given limits.
