slwebview_req

Export Simulink system to Web views with requirements

Syntax

filename = slwebview_req(sysname)

filename = slwebview_req(sysname,Name,Value)

Description

filename = slwebview_req(sysname) exports the system sysname and its children to a web page filename with contextual requirements information for the system displayed on a separate panel of the layered model structure Web view.

filename = slwebview_req(sysname,Name,Value) uses additional options specified by one or more Name,Value pair arguments.

Note

You can use slwebview_req only if you have also installed Simulink^® Report Generator™.

Examples

Export All Layers

Export all the layers (including libraries and masks) from the system gcs to the file filename

filename = slwebview_req(gcs, "LookUnderMasks", "all", "FollowLinks", "on")

Input Arguments

sysname — System to export to web view file

character vector | string scalar | handle

System to export to the web view file, specified as a character vector or string scalar that contains the path to the system or a handle to a subsystem, block diagram, chart, or subchart. By default, the function also exports the child systems of the sysname system. Use the SearchScope name-value argument to export other systems, in relation to sysname.

Example: "sysname"

Name-Value Arguments

Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Before R2021a, use commas to separate each name and value, and enclose Name in quotes.

Example: "ShowProgressBar","off"

SearchScope — Systems to export

"CurrentAndBelow" (default) | "Current" | "CurrentAndAbove" | "All"

Systems to export, relative to the sysname system, specified as one of these values:

• "CurrentAndBelow" — Exports the Simulink system or the Stateflow^® chart specified by sysname and all systems or charts that it contains.

• "Current" — Exports only the Simulink system or the Stateflow chart specified by sysname.

• "CurrentAndAbove" — Exports the Simulink system or the Stateflow chart specified by the sysname and all systems or charts that contain it.

• "on" — Includes referenced models in the web view

• "off" — Does not include referenced models in the web view

FollowSubsystemReference — Whether to export referenced subsystems

"on" (default) | on/off logical value

Since R2024b

Whether to export referenced subsystems, specified as "on" or "off", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState. When you specify:

• "on" — Exports referenced subsystems in the web view

• "off" — Does not export referenced subsystems in the web view

IncludeBehaviorComponents — Whether to include behavior components

"on" (default) | on/off logical value

Whether to include behavior components defined in architecture models, specified as "on" or "off", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState. When you specify:

• "on" — Includes behavior components in the web view

• "off" — Does not include behavior components in the web view

IncludeNotes — Whether to include user notes

"off" (default) | on/off logical value

Whether to include user notes, specified as "on" or "off", or as numeric or logical 1 (true) or 0 (false). A value of "on" is equivalent to true, and "off" is equivalent to false. Thus, you can use the value of this property as a logical value. The value is stored as an on/off logical value of type matlab.lang.OnOffSwitchState. When you specify:

• "off" — Does not display the status bar when you export the web view

Output Arguments

filename — The name of the HTML file for displaying the web view

character vector | string scalar

Reports the name of the HTML file for displaying the web view. Exporting a web view creates the supporting files in a folder.

Tips

A Web view is an interactive rendition of a model that you can view in a Web browser. You can navigate a Web view hierarchically to examine specific subsystems and to see properties of blocks and signals.

You can use Web views to share models with people who do not have Simulink installed.

Web views require a Web browser that supports Scalable Vector Graphics (SVG).

Version History

Introduced in R2015a

R2026a: Option to specify variant subsystems in web view

When generating a model web view, choose which variant subsystems to include by using the propertyIncludeVariantSubsystems. The default behavior is to include all variant subsystems in the model web view.

R2025a: Display parameters for masked Stateflow subcharts in web view

Web views now display mask parameters for masked Stateflow subcharts.

R2024b: Option to exclude referenced subsystems in web view

When generating a model web view, choose whether or not to include referenced subsystems by using the propertyFollowSubsystemReference. The default behavior is to include referenced subsystems in the model web view.
