I want to use ReliefF feature selection algorithm for a dataset(colon), I found this code for ReliefF function from github website (I attached two file ReliefF_Zeal and test_ReliefF) and also Matlab Help is similar to this code
function [Rank, Score] = ReliefF_Zeal(X, y, K)
[Rank, Score] = relieff(X, y, K);
end
but I don't know how to load my data (train and test) in this function, my goal was selecting 30 best features from the data,I'll be very gratefull to have your opinions. Thanks

Hi,
I am also interested about Relief-F for a project and as I understood x is your input data, y is the target, k is a number can be 10(as I understood it depends on your data). But X must have as many rows as there are elements in Y.
