Hi @Mir Sahand
Surrogating data typically involves generating a new dataset that preserves certain properties of the original dataset, such as its mean and variance, but randomizes other aspects to test statistical hypotheses.
Here's a simple way to surrogate your data by shuffling it. This is one of the simplest surrogate data methods:
% Load your data from the Excel file
data = xlsread('your_file.xlsx');
% Surrogate the data by shuffling
surrogateData = data(randperm(length(data)));
xlswrite('surrogate_data.xlsx', surrogateData);
Hope this helps!
