How do I refresh reference model blocks programmatically?
显示 更早的评论
I have a Simulink model with many "Model" blocks. I have to frequently refresh each of these blocks by right-clicking on the block, hovering over "Subsystem & Model Reference", and then clicking on "Refresh Selected Model Block". Is there a way I can update "Model" blocks programmatically?
I'm Using MATLAB 2016b.

Hi Trilok,
It appears that an API for this operation is not available in R2016b. However, I think you can achieve a similar effect by updating the entire model using the following command:
set_param(gcs, 'SimulationCommand', 'update')
Starting from R2020a, the Simulink.ModelReference.refresh command is available, which allows you to update a specific model block as shown below:
modelBlocks = find_system(gcs, 'BlockType', 'ModelReference')
Simulink.ModelReference.refresh(modelBlocks{1})
