Get code configuration from code mappings forSimulink.VariantVariable object
Since R2025a
Syntax
Description
[propertyValue](#mw%5Fe39051c6-f3b3-4aaf-a1c7-b971ef2139c8) = getModelVariantVariable([codeMappingObj](#mw%5F56e70abc-141a-49f2-a319-46ccea9fcd32),[variantVariable](#mw%5Fb6e82e9a-516a-47f0-8460-232b9ea9a15e),[property](#mw%5Faced8c97-02fb-49d7-8fd7-411864c8ede2)) returns the value of a code mapping property for the specified Simulink.VariantVariable object variantVariable (also referred to as a variant parameter) from the code mappingcodeMappingObj. A Simulink.VariantVariable object derives its code mappings from the Simulink.Parameter object that is used to set the Specification property of the object. The getModelVariantVariable function returns the storage class and storage class property settings configured for theSimulink.VariantVariable object from thisSimulink.Parameter object. For code mappings support, theSimulink.VariantVariable object and its associatedSimulink.VariantControl and Simulink.Parameter objects must be defined in the model workspace of the model.
Examples
From the model code mappings for the modelslexVariantParameterCodeMappings, get the name of the storage class of the variant variable GearRatio.
openExample("simulinkcoder/ConfigureCodeGenForVariantParametersInModelWorkspaceExample"); cm = coder.mapping.api.get("slexVariantParameterCodeMappings"); getModelVariantVariable(cm,"GearRatio","StorageClass");
Input Arguments
Name of Simulink.VariantVariable object, specified as a character vector or string scalar.
Example: "GearRatio"
Data Types: char | string
Code mapping property name. The getModelVariantVariable function returns the value of this property. For a storage class defined in the Embedded Coder Dictionary associated with the model, specify a property name or one of these property names.
| Information to Return | Property Name |
|---|---|
| Name of storage class | StorageClass |
| Name of variable for the variant parameter in the generated code | Identifier |
| Name of source definition file that contains definitions for global data that is read by the variant parameter and external code | DefinitionFile |
| Name of get function called by code generated for the variant parameter | GetFunction |
| Name of source header file that contains declarations for global data that is read by the variant parameter and external code | HeaderFile |
| Name of model for which the code generator places the definition for the variant parameter shared by multiple models in a model hierarchy | Owner |
| Boolean value indicating whether the code generator preserves dimensions of a variant parameter that is represented as a multidimensional array | PerserveDimensions |
| Name of set function called by code generated for the variant parameter | SetFunction |
| Name of structure in generated code for the variant parameter | StructName |
| Name of parameter argument tuning service defined in Embedded Coder Dictionary | ParameterArgumentTuningService |
| Name of parameter tuning service defined in Embedded Coder Dictionary | ParameterTuningService |
Example: "StorageClass"
Output Arguments
Name of the storage class or value of the specified storage class property configured for the Simulink.VariantVariable object, returned as a character vector.
