I have a data set Liverxl I attached here. I apply dbscan to this dataset but it didn't give any cluster output, only a value -1. What is the problem with it? Please help me.
clc;
clear;
data=xlsread('Liverxl.xlsx');
asc=sort(data);
minpts=6;
epsilon=4;
[idx, corepts] = dbscan(asc,epsilon,minpts);
gscatter(asc(:,1),asc(:,2),idx);

Your datasets include both values and strings, could be it the problem?
