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.
Simulink PLC Coder does not support variable-size code generation for:
Subsystems that do not have the Function Packaging set to
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:
MATLAB Function Blocks
Variable-Size Code Generation Example
To generate code for a model with variable-size signals, see Generate Structured Text Code for Variable-Size Signals.
