From the MATLAB toolstrip, click the Simulink button . When I run Simulink from the main script, there are no problems. 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. Simulating a model gives you results of the algorithms that you build through the process of modeling. I am sharing it as I found it difficult to find . Start MATLAB ®. In the Test Sequence editor I make a call to the following code as the last step. Simulation. I know that this function is used in simulink to perform the simulation and how actually all these things relate. That Simulink simulation is in turn embedded in a MATLAB script for optimisation purpose. 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 have to feed the inputs to the model one by one i.e. I was able to read the values into a .m file but each input has 11 values (stores as an array). Simulate a model by clicking the Run button on the Simulink Editor, or entering simulation commands, for example, sim and set_param in the MATLAB Command Window or a MATLAB file. We started by trying to identify the ball. Now that the model is complete, you can simulate the model.

Parsim is a convenient and efficient way to run lots of simulations in parallel, either using the local MATLAB pool on your desktop or a MATLAB pool in a cluster. Unfortunately you can't just comment out those lines as the code regenerates new axes each time it's called in the simulation. The amount of time it takes to run a simulation depends on many factors, including the model's complexity, the solver's step sizes, and the computer's speed. Assuming that you have the C compiler installed, Matlab compiles down the model which reduces simulation time. Any help would be appreciated. In some cases, parameters, such as gain, may be calculated in MATLAB to be used in a Simulink model. You can interact with the simulations by pacing the simulation, tuning model parameters, stopping or pausing the . Run Parallel Simulations. For successful integration, you must use either the 64-bit or 32-bit version of MATLAB (Version 2012a or later) to align it with the 64-bit or 32-bit version of modeling tools, e.g., MagicDraw or Cameo Systems Modeler. I am running Simulink using FastRestart, as I need to start and stop the simulation multiple times changing parameters. The problem is that for each Simulink run the time-steps, and therefore the number of data points, are different. Run Multiple Simulations. 3.
