You could use uiputfile to select a file name to be created:

doc uiputfile

(If you want to get a file to load, use uigetfile)

But there is actually a command called uisave which saves variables from the workspace. You just need to tell it what...

doc uisave

To get the variable names from the workspace, use whos:

vars = whos;

Interestingly, you can also do this on an existing .mat file, if you want to choose what to load back later:

vars = whos('-file', 'yourdata.mat');

For list boxes, you need a uicontrol

doc uicontrol

You might want to use GUIDE to help you creating a user interface if you are not comfortable with MatLab or UI programming in other languages.

This is also worth a read:

Hi,

and how can I create popup window, for example like with command "uiputfile" I create popup window- of course more easier :-)...

.

.

.If I create popup window ( if I press any button) and then I load any variable from workspace, so this variable will be available also for parent window? If is not available, how can I make this available for parent window?

Thank you

For your GUI, you need to work through this: http://www.mathworks.com.au/help/techdoc/creating_guis/bqz6p81.html

Yes, you can create a popup GUI, but it takes a bit of code. Use GUIDE to help you with the basics, then just link up the events.

To get variables from the base workspace from within a function, use this: evalin('base', 'whos')

You might look at uipickfiles. Either use it as-is, or study it to see how it's done: http://www.mathworks.com/matlabcentral/fileexchange/?term=uipickfiles
