I want to plot a the sen's slope (linear line) on my time series data, I have already used mann kendall test fuction to see if the trend exist within the data, yes there is trend , but then the next stepis to estimate the sen's slope but I dont understand how this function below really works, please can someone clarify, what is my x and y?

function b = Theil_Sen_Regress(x,y)

[N c]=size(x);

Comb = combnk(1:N,2);

deltay=diff(y(Comb),1,2);

deltax=diff(x(Comb),1,2);

theil=diff(y(Comb),1,2)./diff(x(Comb),1,2);

b=median(theil);

x is the time data and y is your time-series data.

Hi,

You can use a code which is available on following link with title 'MATLAB code for the Mann–Kendall test and Sen's slope estimation for time series data'
