First use @doc:uitabgroup() to contain a container panel .
Then for each section to be put in its own tab, call @doc:uitab() to create a panel.
Then use the panel handle as the parent for the axes() call
Example:
tg = uitabgroup(); %'Position' can be given in normalized units
t1 = uitab(tg);
ax1 = axes('Parent', t1);
plot(ax1, rand(1,20));
title(ax1, 'First tab');
t2 = uitab(tg);
ax2 = axes('Parent', t2);
plot(ax2, randn(1,20));
title(ax2, 'Second tab');
