Do you mean the tick labels?
axes('FontSize', 24, 'NextPlot', 'add');
Without setting the NextPlot property, a plot() command will reset the size - maybe, I cannot try it currently.

Here are a couple of different ways to change axis font size.
x = linspace(-2*pi, 2*pi);
y = cos(x);
plot(x,y);
set(gca,'FontSize',20, 'FontName', 'Courier')
xlabel('x(t)') % Font Size and Name are taken from Line 4 command
ylabel('Y', 'FontSize', 15, 'FontName','Garamound', 'FontWeight','bold')
title("Font Size Change")
%% Alternative way:
fontsize(gca, 13, 'points')
fontname(gca, "SansSerif")
%% Alternative Way:
xlabel('x', 'FontName','Garamond', 'FontSize',10)
%% Axis and Font Color change options
ax = gca;
ax.YColor = 'r';
ax.XColor = 'm';
