vertical lines of 'mean' and 'std' in a 'ksdensity' plot?

Hello everyone. I was wondering how can I add vertical lines of standard deviation, mean, median , among other statistical results to a plot made with the function ‘ksdensity’ ? thank you.

Use xline.

% create a distribution with known mean, std
pd = makedist('Normal','mu',2.5,'sigma',3.1);
x = random(pd,100,1);

[f,xi] = ksdensity(x); 
figure
plot(xi,f);

% Add vertical lines
xline(2.5)
xline(2.5+[-3.1,3.1])

@Cris LaPierre in your expample you know the 'mean', however how can I do it in the case we don't know this value and the dataset has several NaN ?

[Cris LaPierre]

Calculate it.

M = mean(___,nanflag)

mn = mean(x,'omitnan')

@Cris LaPierre how can I display the value of that 'mean' in the left, right side of the line? the x axis? , thanks.
