They don't appear to document that an assignins within evalins don't work. The variable to be saved and the file name Better to call a function and use assignin than have a separate script and use evalin. evalin allows you to treat a data dictionary section as a MATLAB workspace. Use the function handle input to feval whenever possible. Or restructure the code to use functions and inputs/outputs to get a clean and efficient code. Also, there are some instances where you absolutely evalin('base', 'save('var1', 'var2')') I am trying to run a simple function to save specific variables from the base. The eval function fully supports thread-based environments. I have an issue with using evalin within a function that is being called in the body of a parfor-loop.
