modelfinder.searchFilter

Create Model Finder search filter

Since R2025a

Syntax

MFfilter = modelfinder.searchFilter

MFfilter = modelfinder.searchFilter(Name=Value)

Description

MFfilter = modelfinder.searchFilter creates a ModelFinderFilter object MFfilter. You can use the MFfilter object to narrow down the database search results for examples, models, and projects using the modelfinder function.

MFfilter = modelfinder.searchFilter(Name=Value) creates a ModelFinderFilter object MFfilter using one or more name-value arguments. For example, create a search filter object for specific block types and MathWorks^® products. Then, perform a search using a combination of the search term and the filter object with the modelfinder function.

Search Models with Additional Filters

Search for examples and models using a search term, and narrow down the search results by specifying block types and MathWorks product names.

Create a ModelFinderFilter object with specific Simulink^® blocks and MathWorks product names.

blockList = ["ConstellationDiagram",...
             "Rectangular QAM Modulator Baseband"];
productList = ["Communications","5G","Wireless","Satellite"];
mfFilter = modelfinder.searchFilter(block=blockList,product=productList)

   mfFilter = 

  ModelFinderFilter with properties:

        match: [0×0 string]
      product: ["Communications"    "5G"    "Wireless"    "Satellite"]
     location: [0×0 string]
        block: ["ConstellationDiagram"    "Rectangular QAM Modulator Baseband"]
    reference: [0×0 string]

Search for models using a search term and a filter object.

modelfinder("modulation",filters=mfFilter)

modelfinder matches the search term with all the metadata of the examples and models indexed with the MathWorks Examples database and narrows down the results using the specified blocks and product names:

 1. Add Saleh Model of Power Amplifier to 16-QAM Signal in Simulink
        > cm_mnl_saleh_16qam
  2. Apply Phase/Frequency Offset to QAM Modulated Signal

Showing 1-20 of 24 matches. Enter (m) for more results.

Enter the example number you want to open (choose number) 
OR see more results (m) OR quit (q) 
Selection:

Modify the filter object to match the search term with only the names of examples and models indexed in the database.

mfFilter.match = "name"

   mfFilter = 

  ModelFinderFilter with properties:

        match: "name"
      product: ["Communications"    "5G"    "Wireless"    "Satellite"]
     location: [0×0 string]
        block: ["ConstellationDiagram"    "Rectangular QAM Modulator Baseband"]
    reference: [0×0 string]

Search for models using a search term and the modified filter object.

modelfinder("modulation",filters=mfFilter)

modelfinder matches the search term with only the names of the examples and models indexed with the MathWorks Examples database and narrows down the results by using the specified blocks and product names:

   1. Effect of Nonlinear Amplifier on 16-QAM Modulation
        > amp_qam16
   2. Passband Modulation
        > commpassbandmod
Enter the example number you want to open (choose number) OR quit (q):

Running the same query may produce different results depending on the database version.

Name-Value Arguments

collapse all

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.searchFilter(block="gain",product=["communications","5G"]) creates a ModelFinderFilter object to use to filter database search results to include Gain blocks and the MathWorks products Communications Toolbox and 5G Toolbox.

`block` — Names or types of blocks
string scalar | character vector | string array | cell array

Names or types of blocks in a model, specified as a string scalar or character vector for a single block, or a string array or cell array of character vectors for multiple blocks.

Example: block="gain"

Example: block=["Unit Delay","Mux","Ramp"]
