I was trying to use "From Workspace" block but, it gathers the value only once at the beginning of the simulation. I cannot just run a m-code script, save data and then transfer it to Simulink becouse both together need to work with real time vision system. How can I solve that problem?
EDIT:
Thank you very much for your answers. I have tried the solution with S-function that you gave to me, and also by set_param() command, but unfortunately it doesn't work for me how I would like to. The main problem is that there is a need to stop MATLAB script for a moment to let Simulink gather a data, which means I have to use pause() command inside of main for loop of my MATLAB script. If I don't do this, Simulink waits with executing a model at t=0. The problem is that a minimum time for which the m-code script can be stopped by pause() command is approximately 0.0156 s. which is to long for me. That script realize object tracking on the video images from webcam, so such a long pauses causes the fps decrease.
So, my next question, more precise is: Is there any way to stream data from running MATLAB script to running Simulink model without or with just very small delay?
