How can I show Data generated in Simulink in a Matlab GUI?

Hi,

I have a Simulink Model that creates Data. I built a GUI using uicontrol (not GUIDE) that gives parameters to the model (via workspace). A pushputton activates a nested function that gets the inputs and saves them. (get and assignin). Now I run the model (still in nested function), but the To Workspace Block does not work.

Error using GUI_01_FOM_frict/save_input (line 122)

Cannot create variable 'FOM_frict_phi' in workspace

Caused by:

Error using GUI_01_FOM_frict/save_input (line

122)

Attempt to add "FOM_frict_phi" to a static

workspace.

See Variables in Nested and Anonymous

Functions.

Error while evaluating UIControl Callback.

Same Error if call a script which has the sim command

I tried for several hours now to work around that, but I cannot find a solution.

I would appreciate any idea that could help

The Same Error occurs when I use the logging funtion of the Simulink Scope

hello Andre,

you want to read the real-time simulation data from simulink model to GUI ?

regards

ANkit

Hello Ankit,

no, I want to acces the Data after the simulation, no need for real time because the simulation time is maximum 3 seconds.

At this point, I dont have this error anymore because I initialize FOM_frict_Phi = [ ].

But The Data only shows up in this variable when I click Play directly in Simulink, but not when I simulate using Matlab.
