How do we change only the height of the subplots?

I want to increase the height of the subplots in a figure. I checked many MATLAB answers, but unfortunately, nothing is working out perfectly. Recently, I have started commenting on one of the same questions asked (https://uk.mathworks.com/matlabcentral/answers/779797-how-to-change-the-height-of-the-subplots-without-changing-x-y-positions-and-width). I am posting this as a question to get more visibility.

I have also used the suggestion given in 1. https://uk.mathworks.com/matlabcentral/answers/1580549-increase-the-height-size-of-subplots 2. https://uk.mathworks.com/matlabcentral/answers/47713-how-to-increase-figure-window-height

I have seven subplots that I am arranging in four columns and two rows. Here, just for simplicity, I have shown two subplots. Any suggestion would really be helpful to increase the height of each subplot, And how to fix the bottom of the whole figure, which is almost empty. Thanks in advance.

lowerlimit= 0;

upperlimit=300;

interval= 20;

figure()

ax(1)=subplot(4, 4, 1);

h1 = bar(1, ysp1_1, 'b');

hold on

h2 = bar(2, ysp1_3, 'r');

hold on

h3 = bar(3, ysp1_5, 'k');

hold on

h4 = bar(4, ysp1_7, 'g');

hold on

h5 = bar(5, ysp1_9, 'm');

set(ax(1),'xtick',[])

hold off

axis padded

grid;

set(gca, 'ytick', lowerlimit:interval:upperlimit);

ylabel('f0 (Hz)');

title('S1\_F')

ax(2)=subplot(4, 4, 2);

h1 = bar(1, ysp2_1, 'b');

hold on

h2 = bar(2, ysp2_3, 'r');

hold on

h3 = bar(3, ysp2_5, 'k');

hold on

h4 = bar(4, ysp2_7, 'g');

hold on

h5 = bar(5, ysp2_9, 'm');

set(ax(2),'xtick',[])

hold off

axis padded

grid;

set(gca, 'ytick', lowerlimit:interval:upperlimit);

ylabel('f0 (Hz)');

title('S2\_F')

If you are arranging the subplots in four columns and two rows, modify

subplot(4, 4, 1);

to

subplot(2, 4, 1);

and same for the others

Thanks so much.. @Simon Chan Now I understand why there was an empty space in the bottom of the figure :-). It solves the issue.
