Once you have selected this option, you can select any of the following items in the frame to configure ui code. Parallel execution leverages the multiple cores of your host machine to run many simulations more quickly. To be able to access that output in the base workspace, add a command such as this after the sim command. Control parameter values and run matlab simulink from gui.
Simulink software exports final logged state data to the matlab workspace during simulation. Simulink results running the model yields the balls height and velocity as a function of time. Use matlab guis with simulink models file exchange pick. Matlab and simulink are registered trademarks of the mathworks, inc. If the folder in which you save the files is not on the matlab path, guide opens a dialog box that allows you to change the current folder. If you enable the save final operating point parameter, the specified format does not apply to final states data. Saving data to the matlab workspace can consume memory.
