I have a numeric tables that i imported in matlab workspace. I am writing a function called Myfunc in which i have to use the workspace variables (imported table) for a calculation. Then, i call this Myfunc from my main function file (Myfunc_main). My doubt is, how do i define this workspace variable in my main function?

The neatest, easiest, simplest, and by far the most efficient approach is to pass data as input/output arguments:

The MATLAB documentation clearly describes passing data as input/output arguments as "best practice".

Did you try passing the data as input/output arguments?

Exactly. You do not want to somehow magically create that variable in some other MATLAB workspace. That is an extremely inefficient way to do it, and is likely to cause many problems down the line when you try to debug code.

Instead, just return the variable as an output argument of your function. This is both trivial to do, and an efficient way to write it.
