Hi,

I have a simple for loop here and I would like to save the value of variable "a" in each iteration at the MATLAb workspcae. Becaseu I need to read that variable from workspcae simoultaneously and use it in Simulink. I do not need that value after completing the for loop (I could save it in a list), I need that value in real-time (once it gets updated) becaseu it will be used in a Simulink file as an input in real-time.

for i=1:10

a=i;

end

'global' or 'persistent' might satisfy your usecase. Attached below are the documentations for both:

1) Declare variables as global - MATLAB global - MathWorks India

2) Define persistent variable - MATLAB persistent - MathWorks India

I found the solution and wanted to share it here. The "set parameter" function in MATLAB could be used to adjust/change the value of a parameter inside a simulink model in real-time.
