rows = input('Enter matrix size: '); % user input
end_cell = strcat(char(65+rows),num2str(rows));
range = strcat('A1:',end_cell); % if rows = 10, range = 'A1:K10'. If rows = 5, range = 'A1:F5'

M = xlsread('my_excel_file.xls',range); % the matrix you want

While there are a number of good Matlab books out there, you might just want to start with the "Getting Started" section in the Help documentation. Just open Help, and click the "Getting Started" link in that page, and go through those tutorial videos first.
