How do I save variables from a function to the base workspace?
显示 更早的评论
I have a matrix variable, corr_matrix. I would like to save this to the workspace without having to validate (export2wsdlg requests permission before exporting). Can you do this with evalin? I did not understand evalin's documentation...but I would like something like
Save2ws('variable_name', variable);
How can this be done?

What you are asking for with Save2ws is a way to poof a variable. In general this is bad practice. Can you give some details about how/where corr_matrix is being created?

@Pocho if you look around you will see that using eval, evalin, and assignin are considered equally, if not more, evil than globals.

in my script file: inputVT()
in my function file named inputVT.m
I have
v0 = input('velocity');
this works but my input is not stored to the workspace. How do I store it to ws?

In your script,
v0 = inptuVT();
and your inputVT.m would be
function v0 = inputVT
v0 = input('velocity');

If you would like to do this for debugging purposes, you can click on the down-arrow below "Run" and choose "Pause on Errors". This will allow you to browse the internal variables and workspace in a function in debug-mode when an error occurs.

declare them as global variables
global var1 var2 var3
do it in your function and in matlab command

Yes, avoid global variables if you possibly can, which is almost always. Experience debugging code that relied on global variables has taught me this lesson.

@Matt while I try and avoid globals, I would never trade a global for a evalin/assignin. At least globals give you a fighting chance of figuring out what is happening.

If you set variables as global you can not using them in simulikn
