추정을 위해 데이터 선택하기

데이터 서브셋 선택, 추정 및 검증 데이터 지정

함수

`fselect`	Select frequency points or range in FRD model
`getexp`	Get specific experiments from multiple-experiment data set
`merge (iddata)`	Merge data sets into iddata object
`fcat`	Concatenate FRD models along frequency dimension

Specify Estimation and Validation Data in the App
You should use different data sets to estimate and validate your model for best validation results.
Select Subsets of Data
Select portions of data for identification in the app or at the command line.
Create Data Sets from a Subset of Signal Channels
You can create a new data set in the System Identification app by extracting subsets of input and output channels from an existing data set.
Create Multiexperiment Data Sets in the App
You can create a time-domain or frequency-domain data set in the System Identification app that includes several experiments.
Create Multiexperiment Data at the Command Line
You can create iddata objects that contain several experiments.
다중 실험 데이터 및 모델 병합 처리하기
이 예제에서는 System Identification Toolbox™를 사용하여 모델을 추정하고 미세 조정할 때 다중 실험 및 모델 병합을 처리하는 방법을 보여줍니다.
