The global function is nice, for example:

(in GUI):

global y

y=5;

and then in matlab command window i type global y and it is done.

The way I want to do it is that y is automatticaly printed in workspace without me typing global y in command window. Can it be done?

Thanks.

In this link, could you please point a little bit more, where should I look at, because this is a long article and I still cannot find a way to pass GUI input data to workspace.

@Nafiz: I do never create variables remotely in another workspace. I consider this as too confusing and prone to bugs. But if you have a really good reason to do this, it is easy:

assignin('base', 'V', data)

Now the variable V is created in the base workspace (accessible in the command window) and set to the value data.

The linked article concerns another problem: Sharing data between callbacks. Then using the base workspace is a bad idea, because it is much better to store the data inside the figure, in the UserData or ApplicationData, e.g. using setappdata or guidata.
