Is it possible to set varargin from edit text (GUI)?

I made a GUI-based matlab code using GUIDE. I have a function that have a varargin parameter as following:

function stocks = hist_stock_data(start_date, end_date, varargin)

I want to get all the three parameters using GUI input text. Here, varargin is intended for the stocks that will be retrieved from database. Therefore, the number of input should be flexible.

For start_date and end_date, I have done it by the following codes:

start_date = str2num(get(handles.edStartDate,'String')); end_date = str2num(get(handles.edEndDate,'String'));

However, I don't know how to get the varargin (stock data) from edStock.

Thank you for your kind help.

is edStock an edit box? You mention "retrieving from database", what does that mean: do you input something in an editbox and that is used to make a query?

Thank you for your comment, Sara. The stock was retrieved from Yahoo! Finance's database. The function will be invoked as something like hist_stock_data('01011995','01072014','^FTSE', '^FTAS'). FTSE and FTAS are companies listed in Yahoo! Finance stock. I need to make the system to be dinamic, so user can load data from other companies as well, say it will be something like hist_stock_data('01011995','01072014','^GOOG'), means that it will take Google stock.

So, is your edBox where the user inputs what database to use, e.g. the user could write GOOG in there and your code go grabbing the right stock?

Yups. But the user may have one or several stock(s) to retrieve.
