+\title{S3 class constructor for storing frequency response data}
+\usage{
+idfrd(respData, freq, Ts, spec = NULL, covData = NULL, noiseCov = NULL)
+}
+\arguments{
+\item{respData}{frequency response data. For SISO systems, supply a 
+vector of frequency response values. For MIMO systems with Ny 
+outputs and Nu inputs, supply an array of size c(Ny,Nu,Nw).}
+
+\item{freq}{frequency points of the response}
+
+\item{Ts}{sampling time of data}
+
+\item{spec}{power spectra and cross spectra of the system 
+output disturbances (noise). Supply an array of size (Ny,Ny,Nw)}
+
+\item{covData}{response data covariance matrices. Supply an array
+of size (Ny,Nu,Nw,2,2). covData[ky,ku,kw,,] is the covariance matrix
+of respData[ky,ku,kw]}
+
+\item{noiseCov}{power spectra variance. Supply an array of 
+size (Ny,Ny,Nw)}
+}
+\value{
+an idfrd object
+}
