Is there a way to save a variable created in a function to the workspace?

I have a variable being created in a function and want to save in the workspace so the command window can access.

Answer 1

[Oleg Komarov]

the syntax of a function could be summarized as:

[output1, output2, ...] = function(input1, input2, ...)

Say, yuor variable is named X in the function, then all you need to do is:

X = function(...)

If you call the function as:

function(...)

your variable will be assigned automatically to ans, otherwise to

anyname = function(...)

anyname will be what is X in your function.

As Aldin pointed out, if you're in a GUI then use:

assignin('base','someName',X)

Answer 2

[Aldin]

If you working in GUI i THINK that's impossible. It is an mistake in MATLAB because the data are not permanent as in Java.

[Oleg Komarov]

generally, to swap variable from any specific workspace to the base one you can use:

assignin('base','someName',yourvar)

[Aldin]

Hi Oleg. Sorry for my behavior. Thank you. I didn't know that.I think It would be better for MATLAB to think object oriented.

I think "persistent" will help.

Just use

persistent variable_name = value

[Walter Roberson]

That is not valid syntax. You can use

persistent variable_name

to indicate that the variable keeps its value between calls. You cannot, though, initialize it in the same statement, and doing so would be a waste of the idea that you want to pull back the value the variable had in the last function call.
