Set the 'Position' property of the individual axes to resize them.

You can use text() to place text, or use suplabel: https://www.mathworks.com/matlabcentral/fileexchange/7772-suplabel

% Create 4 subplots.
h1 = subplot(2, 2, 1);
h2 = subplot(2, 2, 2);
h3 = subplot(2, 2, 3);
h4 = subplot(2, 2, 4);
% Change size and location of subplot#1
h1.Position = [.1, .6, .2, .3]
