repr_dct {TSrepr}

DCT representation

Description

The repr_dct computes DCT (Discrete Cosine Transform) representation from a time series.

Usage

repr_dct(x, coef = 10)

Arguments

x

the numeric vector (time series)

coef

the number of coefficients to extract from DCT

Details

The length of the final time series representation is equal to set coef parameter.

Value

the numeric vector of DCT coefficients
