merge (iddata) | Merge data sets into iddata object |
fcat | Concatenate FRD models along frequency dimension |
Temas
- 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
iddataobjects that contain several experiments. - Dealing with Multi-Experiment Data and Merging Models
This example shows how to deal with multiple experiments and merge models when working with System Identification Toolbox™ for estimating and refining models.
