Discrete Hartley Transform

DESCRIPTION:

Computes the discrete Hartley transform (DHT) of a vector.

USAGE:

dht(x, inv=F) 

REQUIRED ARGUMENTS:

x
a time series or a vector.

OPTIONAL ARGUMENTS:

inv
logical flag: if TRUE, the inverse of the transform is computed.

VALUE:

the normalized discrete Hartley transform of the input data x (or the inverse transform if inv=TRUE). This is of the same length and mode of x.
