Good day.
I have a MATLAB function which I run from a script. I want to plot some variables in the function from my script so I want to save these variables in my workspace. Is there any way to do it other than using them as an output to the function when I call it from the script? The variables are many so I am trying to avoid too many output arguments.
Thanks now and always.

Messing around with assignin or lots of output variables is not a good approach.
Just assign the variables to fields of a structure and return that. Simple.

Use assignin command
function y = test()
assignin('base','x',42)
y = 0
end

this works only if you run your function first and then run your script to plot the variables of course

You could also consider placing the variables in a structure. That way, your function only needs to have one output, yet all the variables can be passed out.

Just to clarify, that wasn't Stephen's suggestion. His recommendation was NOT to do that. He suggested using a structure, as did I. That would likely be the quickest approach since you don't have to write the variables to the workspace or the harddrive.
