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:

I was able to pass my variables in between base workspace and gui and also call back functions through this. Thanks!

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.
