|A frame-based variable-size signal cannot change the frame length (first dimension size), but it can change the second dimension size (number of channels). Using frame-based signals requires DSP System Toolbox™ software.||Use the Frame Conversion block to convert a signal into sample-based signal.|
|Variable-size signals must have a discrete sample time.||—|
|Embedded Coder® does not support variable-size signals with ERT S-functions, custom storage classes, function prototype control, the AUTOSAR, C++ interface, and the ERT reusable code interface.||—|
|Simulink® does not support variable-size parameter or DWork vectors.||—|
|Rapid accelerator mode does not support models having root-level input ports with variable-size signals.||—|
