MATLAB: Do I receive an error loading initial state when building a subsystem with Real Time Workshop 6.3 (R14SP3)

simulink coder

When I build a subsystem with the right-click Real-Time Workshop -> Build Subsystem, I receive the following error:

 Error loading the initial state for model 'Subsystem'. Unable to find a matching block state corresponding to element 1 of signals structure array

Best Answer

In order to be able to build a subsystem properly, the initial state variable, which is set in the model's Configuration Parameters (Data Import / Export) must be an array that corresponds solely to the states in the subsystem.

Follow the steps below to set the initial state variables as array:

- Open the Configuration Parameters -> Data Import/Export pane

- Check the boxes with 'Time' and 'States', select the 'Format' option to 'Array'

The simulation results obtained are different since the final state is saved as an "Array". To resolve this issue, save the final state in the "Structure with time" format, instead of "Array". Selecting this option ensures consistent ordering of the states.

Hello William,

I understand that you are getting an error following the documentation steps. The doc seems to have an error in it.

Please change the init callback to this:

load('myModel_init');

Hope that helps.
