Hi,
I understand that you have the error message that the block "CruiseMatlabDLL5/Subsystem3/Subsystem/Chart" does not fully set the dimensions of the output "status". This problem typically arises due to misconfiguration or omission of settings related to signal properties. To address this, consider the following steps:
- Check Block Parameters: Open the chart block "CruiseMatlabDLL5/Subsystem3/Subsystem/Chart. Verify that the output signal “status” is correctly defined in the block parameters. The signal should have a valid name and dimensions. Ensure that all output signals are initialized properly at the start of the simulation as an incorrect initialization might lead to undefined dimensions during the simulation's early steps.
- Signal Dimensions: Confirm that the dimensions of status are consistent with other signals connected to the chart. The dimensions (size) of “status” should match your intended design. Ensure you have explicitly defined the dimensions of the output signal within the Stateflow chart. This can be done as follows:
- For Data Store Write: If you're writing to a data store, make sure the data store memory block that corresponds to your output signal has the correct size specified.
- For Output Data: Navigate to the "Chart Properties" or "Data Properties" panel where your output data is listed. Then, check the "Size" property of the output data and ensure it matches the expected dimensions.
- Data Types and Dimensions: Check the data type of "status". It should match the expected data type (e.g., boolean, integer, etc.). If "status" is a vector or matrix, ensure that its dimensions are explicitly set (e.g., using the size function or specifying the dimensions directly). Verify that the data types of your signals are compatible. Mismatched data types can cause dimension-related issues. If necessary, explicitly specify the data type for your signals.
- Signal Connections: Check if the output signal is connected to other blocks or components within your model. Incorrect connections can lead to dimension-related errors. The signal should be connected to the appropriate input ports of other blocks. Ensure the data scope of your output signal is set correctly (e.g., "Output" for signals that should be output from the Stateflow chart to the Simulink environment).
- Sample Time: Confirm that the sample time of your output signal is consistent with other signals in your model. Inconsistent sample times can result in dimension errors.
- Debugging:
- Inspect the workspace variables to ensure that the signal dimensions are correctly set.
- Double-check the logic within your Stateflow chart to ensure that the output signal is being assigned a value of the correct dimension in all possible execution paths. It's possible that some paths through the chart do not assign a value to the output signal, leading to dimensionality issues.
- Go to the "Model Configuration Parameters" > "Diagnostics" > "Data Validity". Check the settings under "Signal Infractions" and "Dimension Mismatch". Adjusting these settings might provide more detailed warnings or errors that can help in diagnosing the issue.
By methodically checking these areas, you should be able to identify and resolve the issue with the undefined output signal dimensions in your Stateflow chart.
I hope this helps!
