RapidAccelerator - rtp returns empty 'parameters' structure

Good day,

I'm having problems getting a parameter structure when building the RapidAccelerator mode for running a Simulink model.

rtp = Simulink.BlockDiagram.buildRapidAcceleratorTarget(model,'AddTunableParamInfo', 'on')
rtp = 

    modelChecksum: [2.4392e+09 825977970 3.1169e+09 4.0394e+09]
       parameters: []

problem: 'parameters' --> empty structure. Settings: Optimization > Signal and parameters > 'Inline parameters' is checked in and the required Tunable Parameter list was added to the table from the Matlab Workspace.

Why does rtp return empty parameters structure? I need this 'rtp' so I can go on with my coding for running the model in a loop where the tunable parameter values changes with each iteration.

I have tried the following commands on the demo model 'vdp':

   >> vdp
   >> rtp = Simulink.BlockDiagram.buildRapidAcceleratorTarget(bdroot,'AddTunableParamInfo', 'on')

   >> rtp.parameters

This gives the expected result. However, the Inline Parameters optimization is unchecked in this case and this can be verified from

   >> get_param('vdp','InlineParams')

Now, setting this parameter to on:

   >> set_param('vdp','InlineParams','on')
   >> rtp1 = Simulink.BlockDiagram.buildRapidAcceleratorTarget(bdroot,'AddTunableParamInfo', 'on')

   >> rtp1.parameters

This results in an empty 'parameters' field in the structure. The reason being the parameters are inlined. Therefore, if you want to use these parameters in the command line, I suggest you to un-check the Inline Parameters option.
