whos

(Not recommended) List name and type of objects inside ModelDataLogs, SubsysDataLogs, or TSArray object

The ability to log and load data using the ModelDataLogs format has been removed. Use another supported format, such as Dataset format, instead. For more information, see Compatibility Considerations.

Syntax

whos(logs)

whos(logs,opt)

Description

whos(logs) lists the name and type of each top-level object inside the data logging object logs.

whos(logs,opt) lists the name and type of the objects inside the data logging object logs according to the option opt.

Input Arguments

logs — Logged data

Simulink.ModelDataLogs object | Simulink.TSArray object

Logged data, specified as a Simulink.ModelDataLogs object or a Simulink.TSArray object.

opt — Objects for which to list name and type

'systems' | 'all'

Objects for which to list name and type, specified as 'systems' or 'all'.

• 'systems' — List name and type of all objects except Simulink.Timeseries objects inside a nested Simulink.TSArray object.

• 'all' — List name and type of all objects.

Version History

Introduced before R2006a

R2022b: Loading data saved in the ModelDataLogs format no longer supported

Starting in R2022b, you can no longer load data stored in the ModelDataLogs format, including data stored in Simulink.Timeseries, Simulink.TSArray, and Simulink.SubsysDataLogs objects.

You can convert data stored in the ModelDataLogs format to the Dataset format. For more information, see Convert Data to Dataset Format.

R2021a: Loading data saved in the ModelDataLogs format will not be supported

When you load data that uses the ModelDataLogs format as input for simulation, the software issues a warning that support for loading data in the ModelDataLogs format will be removed in a future release.

R2020b: Loading data saved in the ModelDataLogs format will not be supported

In a future release, the ability to load data that uses the ModelDataLogs format as input for simulation will be removed.

R2016a: Logging data using ModelDataLogs format no longer supported

Starting in R2016a, you can no longer log data using the ModelDataLogs format, and signal logging always uses the Dataset format. When you open a model from a previous release that had logged data using ModelDataLogs format, the model configuration parameters are updated to log data using the Dataset format instead.

You can still use and access data logged using the ModelDataLogs format in previous releases, including data in Simulink.SubsysDataLogs, Simulink.TSArray, and Simulink.Timeseries objects. You can also convert data saved in the ModelDataLogs format to the Dataset format, which can simplify data processing. For more information, see Convert Data to Dataset Format.
