Preparing Data :: Using System Identification Toolbox Blocks (System Identification Toolbox™)

System Identification Toolbox™

Preparing Data

The following table summarizes the blocks you use to transfer data between the MATLAB and Simulink environments.

After you add a block to the Simulink model, double-click the block to specify block parameters. For an example of bringing data into a Simulink model, see the tutorial on estimating process models in the System Identification Toolbox Getting Started Guide.

Block Description

IDDATA Sink Export input and output signals to the MATLAB workspace as an iddata object.

Block	Description
IDDATA Sink	Export input and output signals to the MATLAB workspace as an `iddata` object.
IDDATA Source	Import `iddata` object from the MATLAB workspace. Input and output ports of the block correspond to input and output signals of the data. These inputs and outputs provide signals to blocks that are connected to this data block.

IDDATA Source

Import iddata object from the MATLAB workspace.

Input and output ports of the block correspond to input and output signals of the data. These inputs and outputs provide signals to blocks that are connected to this data block.

For information about configuring each block, see the corresponding reference pages.
