| Array format logging does not support variable-size signals. | Use a structure or a structure with time format for logging
variable-size signals. |
| Right-click signal logging does not support variable-size signals. | Use a To Workspace block or a root Outport block for logging
variable-size signals. |
| 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. | — |
| A scalar signal (width equals 1) cannot
be a variable-size signal because the maximum size is 1. | — |
| 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. | — |
