So here's my graph
I would like to flip the axis markers for each point to the opposite side and add more markers in between each point but that are smaller. How do I do this?

Ran in:
plot(rand(20,3))
h=gca;
h.XMinorTick = 'on';
h.TickDir = 'out';

Ran in:
Try something like this —
x = logspace(-4, 5, 500);
y = 1-exp(-0.2*x) + sin(2*pi*x*1E-4)*0.1;
figure
semilogx(x, y)
Ax = gca; % gca = 'Get Current Axes' Handle
xt = log10(xticks);
N = 5; % X-Tick Frequency Multiplication Factor
xtn = linspace(min(xt), max(xt), numel(xt)*N);
lxtn = 10.^(xtn);
Ax.XTick = lxtn;
Ax.XTickLabel = round(log10(lxtn),1);
Ax.XDir = 'reverse';
EDIT — Added a short explanation of gca as a % comment. No other changes in the code.
