Variable-Size Signal Code Generation

To generate code for your Simulink^® subsystems, Stateflow^® charts, and MATLAB^® Function Blocks that have variable-size signals, use Simulink PLC Coder™. An array that has at least one variable dimension is called a variable-size array. Variable-size arrays are commonly found in applications such as machine learning and deep learning. Construct variable-size signals in your model by using Simulink blocks, MATLAB Function Blocks, and Stateflow charts. For more information, see Variable-Size Signal Basics.

Limitations

Simulink PLC Coder does not support variable-size code generation for:

• Subsystems that do not have the Function Packaging set to Inline.

• Do not use one-dimensional variable-size inputs and outputs in the top-level subsystem.

• Selector blocks that have variable-size data.

Simulink PLC Coder supports only these model components for variable-size code generation:

• Simulink subsystems

• MATLAB Function Blocks

• Stateflow charts

Variable-Size Code Generation Example

To generate code for a model with variable-size signals, see Generate Structured Text Code for Variable-Size Signals.
