Syntax

Simulink.data.getVariableFromGlobal(modelName,variableName)

Description

Simulink.data.getVariableFromGlobal(modelName,variableName) retrieves the value of the variable variableName within the context of the Simulink® model or a Subsystem Reference block specified by modelName. The search includes the base workspace and the external data sources linked to the model, such as Simulink data dictionary or MAT files.

If the variable is found, the function returns its value. If the variable does not exist within the context of Simulink model or a Subsystem Reference, the function reports an error.
