axis in scientific form - have tried to stop it….
I have a plot with a logarithmic scale on the x-axis and I want it to say the numbers like 1,10,100,1000 etc. and not 10^0, 10^1, 10^2 etc. It'd be great if someone could help me do that.
I've given it about 20 minutes just now and I gave it 20 minutes yesterday too and I still can't get it to work. I've left my attempt on the bottom anyway.

m = 0.05;
k = 1000;
R = 1;
f = linspace(0,19999,20000);
Xm = m.*(2*pi.*f) - k./(2*pi.*f);
createfigurelog(f,Xm);
%set(gca,'XTick', [0,1,10,100,1000,10000]); %set(gca,'XTickLabel',sprintf('%3.4f|',f))

curtick = get(gca, 'XTick');
set(gca, 'XTickLabel', cellstr(num2str(curtick(:))));
The scientific notation is not used if the tick labels are set.
Also note the "trick" of passing a column vector to num2str.

I may be making a rookie mistake, but this approach doesn't seem to work for loglog( ) in R2018b.
The command (ax.XRuler.Exponent = 0) executes without an error, with ax set to gca, but the axis properties don't change.
The other method with
get (gca, 'XTick')
etc. does still work with loglog( ) in R2018b.

The Exponent is intended to deal with the situation in which the end of the ruler has an exponent written in, such as
x = linspace(0,5,1000);
y = 100*exp(x).*sin(20*x);
ax = gca;
plot(ax, x, y)
ax.XRuler.TickLabel
ax.XRuler.TickLabelFormat
However, when you use loglog() then those end-of-ruler exponents are not written in.
loglog(ax, x, y)
ax.XRuler.TickLabel
ax.XRuler.TickLabelFormat
The only XRuler properties I look at that appears to control this automatic writing-in of formatted ticks is Scale
loglog(ax, x, y)
ax.XRuler.Scale = 'linear';
ax.XRuler.TickLabel
My initial guess was that TickLabelFormat would control it, but it does not -- and I realized that there is no % format specifier for raised exponent so TickLabelFormat could not control it.
