Hello All,
I wanted to know if anyone knows if it's possible to pass arguments to a matlab script file, perhaps similar to the built-in commands like clear.
My motivation for wanting to do this instead of using a function file is that in my case, I would strongly prefer all variables used to remain in the workspace so that I can continue playing around with them. One option would be to put everything into a struct and have the function output that struct, but this is very cumbersome and muddles up the script. Thus far I've been putting flags at the beginning of the script (such as "save = true" or "filename = 'FN'") and commenting and uncommenting them as necessary, but as their number has grown and I switch more frequently it would be great to be able to avoid having to open and edit the file so frequently.
Many thanks! Andrew

What exactly do you mean by "pass arguments to a script file" anyway? Since scripts share the workspace of their caller, all parameters in that workspace are already available to the script.

This FEX submission makes it very easy to export variables to the base workspace
W = who;
putvar(W{:})

My recommendation would be to use a function file, not a script, but to insert a KEYBOARD statement as the last line in the file. Then when the function completes, you will stay inside the workspace of the function and can continue to play around interactively with the variables there.
This is even a bit safer than what you propose, because every time you call the function, you will always start with a clear workspace. With scripts, it's very easy to forget about the effects on the workspace of previous runs.

This is really helpfull solution to turn any function into script and any script into function.
Also, may be helpful for debug.

Rather than using assignin and eval to do your debugging, use the debugging tools included in MATLAB to debug your functions.
