modelfinder

Search and open examples, models, and projects

Since R2022a

Syntax

modelfinder(searchTerm)

modelfinder(___,Name=Value)

Description

modelfinder(searchTerm) displays a numbered list of examples, models, and projects available in the databases that match the search term and prompts you to enter a corresponding number to open any search result. Other options in the prompt include q to quit and m to see more results. Search results that appear indented and prefixed with > are Simulink^® models that are a part of an example or project.

Model Finder supports keyword-based searches and natural language queries. When you enter a search term, Model Finder matches your search term with the metadata of the examples and models indexed in the databases selected for searching. The metadata includes model names, example names, model paths, description, annotation, block names, block types, MathWorks^® products, and referenced files.

By default, modelfinder searches the MathWorks Examples database. For information on setting search databases with Model Finder, see modelfinder.setSearchDatabase.

modelfinder(___,Name=Value) specifies search options using one or more name-value arguments in addition to the input argument in the previous syntax. For example, set filters to the name of a ModelFinderFilter object to narrow down searches based on parameters such as model locations, block types, or MathWorks products.

Input Arguments

searchTerm — Search string

string scalar | character vector

Search string to find examples, models, and projects in selected databases, specified as a string scalar or character vector. Searches are case-insensitive and disregards special characters. Model Finder matches the search string with the metadata of the examples and models indexed in the databases selected for searching. The metadata includes model names, example names, model paths, description, annotation, block names, block types, MathWorks products, and referenced files.

Example: "autosar"

Example: "pmsm models using discrete pulse generator"

Data Types: string | char

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.

Example: modelfinder("modulation",filters=mfFilter,verbose="on") searches for models containing the search term modulation and narrows down the search results by using a ModelFinderFilter object mfFilter. With the verbose name-value argument set to "on", it also displays additional information related to the search results.

filters — Filter

ModelFinderFilter object

Filters used to narrow down the search results based on MathWorks product names, model locations, block types, or external referenced files, specified as a ModelFinderFilter object. To create a ModelFinderFilter object, see ModelFinderFilter.

Example: filters=mfFilter

view — Option to customize search results layout

"Categorized" (default) | "Models"

Option to customize the search results layout, specified as one of these values:

• "Categorized" — Display search results as a numbered list of examples and models. Simulink models that are a part of an example or project appear indented and prefixed with >.

• "Models" — Display search results as a numbered list of models. The search results include independent models and models that are referenced by examples and projects.

Example: view="Models"

Data Types: string | char

verbose — Option to display additional information related to search results

"off" (default) | "on"

Option to display additional information related to the search results, specified as one of these values:

• "off" — Display only the names of the matched examples, models, and projects.

• "on" — Display the names of the matched examples, models, and projects with these additional details:

  • Source — Example name.

  • Matched in — Metadata of examples and models that matches the search terms. The metadata includes model names, example names, model paths, description, annotation, block names, block types, MathWorks products, and referenced files.

  • Matched text — Matching search terms.

Example: verbose="on"

resultsPerPage — Number of search results displayed per page

20 (default) | double

Number of search results displayed per page, specified as a numeric scalar.

Example: resultsPerPage=5

Data Types: double

Alternatives

You can search databases by using the Model Finder user interface. For more information, see Model Finder.

Version History

Introduced in R2022a

R2025a: Support to filter database searches

Narrow down the search results based on several parameters, such as the MathWorks product names, model locations, block types, and referenced files by using a ModelFinderFilter object.

R2025a: Option to customize search results layout

Customize the search results layout to display the results either as a list of examples with their supporting models or a list of models alone.

R2025a: Change in name-value argument

Filtering search results using name-value argument blocks is not supported. Use the filters name-value argument instead.

R2023b: Support to search additional databases

In addition to the MathWorks database of examples and models, you can add additional search databases to Model Finder using the modelfinder.setSearchDatabase function and search for models in these databases.
