partrepo.importDataSetsFromJSON

Import block data sets from a JSON file

Since R2025a

Syntax

PartDataSets = partrepo.simscape.importDataSetsFromJSON(FileNames)

Description

PartDataSets = partrepo.simscape.importDataSetsFromJSON(FileNames) returns a cell array of BlockDataSet objects imported from the files, FileNames.

Examples

Import block data set from JSON file

This example shows how to create a block data set, store it in a JSON file, and then import the data set from the JSON file.

Create a model that contains a Simscape block. This example uses a Capacitor block from the Foundation Library.

modelName = "myModel";
close_system(modelName,0) 
libraryBlockName = "fl_lib/Electrical/Electrical Elements/Capacitor";
open_system(new_system(modelName));
blockName = add_block(libraryBlockName,modelName + "/" + "Example block");

Create a block data set from the Capacitor block.

myDataSet = partrepo.simscape.dataSetFromBlock(blockName)

myDataSet = 

  BlockDataSet with properties:

            ID: "||" (format)
      Metadata: [1×1 Metadata] (11 entries, Incomplete)
    Parameters: [1×1 Parameters] (3 entries)

In the Metadata property of the BlockDataSet object, add values for the Manufacturer and PartNumber properties.

myDataset.Metadata.Manufacturer = "My Manufacturer";
myDataset.Metadata.PartNumber = "U312_45";

Export the block data set to a JSON file. Use the part number as the file name.

partrepo.exportDataSetsToJSON(myDataset,myDataset.Metadata.PartNumber)

Import the block data set from the JSON file and display the data.

results = partrepo.importDataSetsFromJSON('U312_45.json');
disp(results{1})

myDataSet = 

  BlockDataSet with properties:

            ID: "My Manufacturer|U312_45|" (format)
      Metadata: [1×1 Metadata] (11 entries)
    Parameters: [1×1 Parameters] (3 entries)

Input Arguments
