Hello everyone,

I have a large simulink model. In this model I calculate certain variables that are essentially [1x1] constants. For example, I analyze an electrocardiogram recording to count the number of heart cycles: num_cycles.

I would then like to use such constants like num_cycles in various other blocks like selectors and Matlab function blocks to fix the size of various variable size signals.

Now, if such constants would be defined in the workspace, I could just type num_cycles or whatever in the Simulink selector block, or in the output size of the Matlab Function's explorer. I have tried using the block "ToWorkspace" to do this. However, this block only sends data to workspace once the simulation in stopped or paused.

My question is: is there any way to send variables to the workspace immediately so that they can be accessed by future blocks as if they were workspace variables?

Thank you,

Rafael

I don’t think you can do this. Please post here if you find a solution.

However, the answer may be in your question. Did you read the doc on “variable size signals”?
