\title{S3 class for storing frequency response data}
\usage{
idfrd(response, freq, Ts)
}
\arguments{
\item{response}{complex vector/matrix containing the response}

\item{freq}{the frequencies at which the response is observed/estimated}

\item{Ts}{sampling time of data}
}
\value{
an idfrd object

\description{
S3 class for storing frequency response data
}
\note{
The class can currently store only SISO Responses. Future versions will 
have support for multivariate data
