Hi all, I want to run a simulation from a matlab script (or function) using workspace variables as parameter values for constant blocks in the simulation. I want to be able to pause the simulation at a specific time (say 10 seconds in) and change the value of the constant, then resume the simulation. Is there a way to do this. As a simple descriptive example, lets say I have a simulation which plots A*sin(wt) in a scope. 'A' and 'w' are constant blocks with values which are defined in the workspace with A=1 and w=1. At 1 second into the simulation, I want to pause it and change A=2, then continue the simulation. Is it possible to do this in a matlab script? If so, please let me know how.

"sim" is the name of the function which can run the simulation from through programming. check the link below for more details

Thanks Kintali, I know about the "sim" command; however, I am unsure how to subsequently pause the simulation, change constant values (in the script), and resume. Do you know how this is accomplished?
