You could achieve this by modifying the "Position" (or "OuterPosition") property for each of the five individual "axes".
For example to reduce the "Width" and "Height" for each of the five individual axes to 50%, please see the code snippet below:
figure
for ii = 1:5
subplot(1, 5, ii)
plot(ii, sin(ii));
tmp=get(gca,'position');
set(gca,'position',[tmp(1) tmp(2) 0.5*tmp(3) 0.5*tmp(4)])
end
For more information on "axes properties", please refer to the following documentation page:
