@HN: global variables and evalin are two anti-pattern options that you should definitely avoid using, unless you really want to force yourself into writing slow, compplex, obfuscated, buggy code that is difficult to debug.

The MATLAB documentation clearly states the the best practice is to pass input/output arguments:

agreed @Stephen - it's hideous and obscure...(but possible)

The best option is to pass them to the function as extra parameters. See: Passing Extra Parameters for an extended discussion.

I found it a bit harder to catch up the pass variable. Can you be a bit more specific please. Example.

When I run the for loop W is saved into the workspace. After finishing the for loop I wanted to use W inside fqdot function. How can I pass W into this funciton to compute omg?

Thank you so much for the help.

Please see the documentation on Passing Extra Parameters that I linked to in my original post.

I have no idea what you are doing in your code (other than it appears to be a Runge-Kutta integrator).
