If you want to access data that is in base workspace in your gui functions, use
v = evalin('base','name of variable u want to access'); % the variable's data is now stored in v. If u want to save data of ur gui work space to base, use
assignin('base','name of variable u want to save','value of variable'); Several ways are shared in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_share_data_between_callback_functions_in_my_GUI.28s.29.3F

This might be what you want
Also, you can pass MATLAB variables to the GUI as input arguments when it is initially launched:
The variables A,B,C,... will be passed to your gui's OpeningFcn, assuming you developed the gui using GUIDE, as varargin inputs.

You can import a file from the file system using uigetfile() to get its filename, then use functions such as dlmread, csvread, textscan, importdata, etc. to read in the contents of the file.
