I have edited the question to make it readable. See http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup. Didn't you see, that the missing format impedes the readability?

matObj = matfile('YourFile.mat');
details = whos(matObj);
[maxBytes, index] = max([details.bytes]);
maxName = details(index).name;
Now explain what "pick the variable" means. Do you want to import this variable?
data = matObj.(maxName);
% Or
data = load('YourFile.mat', maxName)
