to receive data from simulink and send to app designer

i am working on app designer. i have built an application through app designer . Now i want to receive data from simulink model in real time to update my app designer editfield. i dont know how to do this . please if somebody can help me in this issue. THANKS

one option would be to have some to workspace blocks in the simulink file: Log data to workspace from Simulink model - Simulink - MathWorks Switzerland. You just connect them to the signal you want to log and upon simulation it will put the in the workspace in the format you choose (array, timeseries, struct,...).

Now you can store them in a variable and so update the app.

In pseudocode:

%let's say you placed a 'to workspace' block that gives you a struct 'out' with 3 signals 'a,b,c'

out=sim(<slxFileName>); %simulates and logs the signals in a variable

updateApp = plot (out.tout,out.a); %tout is the time of the simulation and will be logged in the struct automatically

The plot is just a simple example, you should use the now logged values in app functions as you prefer.

can you gave me an example for this method?

this is the simulink side:

let's say you want the this saturated ramp to log it on your app for some reason.

the 'to workspace' block on the bottom right corner will output the ramp array (and the simulation time) to a struct in the matlab workspace upon simulation (see code in the previous answer). From there, since they are stored in an accessible variable, you can use their values to update you app.
