Thank you. Also, where can i dowbload your script ?

[@mihirsanjay4577]

for those who are using R2021b some tweaks are to be made as described below 11:42 you will see an extra variable (probably named ans) in your workspace once 'sim('PendulumModel.slx')' command is executed. 13:55 Now after that when you create an outport(yout) in simulink and run the code, you wont see any other variable getting added to your workspace. that is because the 'yout' variable will be created under the variable that was previously generated(probably named ans). Due to this you wont get the output you are expecting, to get the appropriate output just change code line, at 15:17 thetasignal = yout.getElement('theta'); to thetasingal = ans.yout.getElement('theta'); also to check the yout variable in command prompt , 14:05 type 'ans.yout'+enter 19:31 to get signal dimensions go to debug ------> information overlays ------->signals------->signal dimensions 23:58 'simX' & 30:38 'logsout' is similar variable to 'yout'. Change the code in similar way.

[@ahungryflyer]

AE501: Great intro to getting matlab to talk to simulink. I was using R2020b and had some trouble getting "yout" to work correctly like your video. Had to go to model settings -> data import/export -> "uncheck" single simulation output and all worked perfectly. I guess mathworks must have modified that between 2016b and now.

[@ChristopherLum]

Andrew, thanks for pointing this out, this is very helpful for users with R2020b. There were indeed some changes made between Matlab versions. As such, be careful in future demos and you may need to make small tweaks.

[@rowellcastro2683]

AA516: Thank you for this tutorial Professor! It might be a little bit confusing to some with the newer versions and how the data are structured slightly different but getting help from mathworks and directly clicking the data outputs to see what is stored in there will solve most of the issues. Thanks.

I'm glad you are able to reconcile the differences. This is a powerful mechanism and we'll use this a lot in the future.

Great Video!! Very good explanaitions, very good speed an great examples!!

[@SomeoneCommenting]

Although at 15:27 he shows you how to extract the time signal from the structure (which is nice to learn how to extract any signal from a structure), every simulation will always give you the time vector for the whole thing in the variable *tout* , which you don't need to define because the model will output it by default for you. That *t* that he defined is already *tout* if you wanted to use it. You can see in the variables section that they will both end having the same dimensions, a vector of 903 elements.

[@Apocobat]

Idk if its a quirk or I missed something in the video, but in order to access yout, I have to use out.yout as everything from the model is stored in an out parameter. Not sure why this is, and it seems like not many have this issue, but regardless, this is super helpful and will help me automate a ton of stuff. I'm working with motor models as a side project and running different parameters, voltages, etc and recording steady state/time delay etc and plotting, something that I knew could be done, but had no idea how to do it, seems very possible now. If i wanted to sweep 3-24V, record the steady state to an array, and plot the array, I could very easily do this, even juggling multiple models (comparing simulink parameters and simscape physical sims). This will save me a ton of time, thank you
