Those functions are designed to work with text files and other types of files.
Read the documentation, that's why I provided links. There's a bit of a learning curve to using these functions since they have many different options but that's all explained in the documentation along with examples. Walter Roberson's answer shows you how to do this and each of those steps are explained in the links I provided above.

filename = 'https://www.mathworks.com/matlabcentral/answers/uploaded_files/592115/D11.csv';
opt = detectImportOptions(filename, 'readvariablenames', false, 'headerlines', 9, 'extracolumnsrule', 'ignore');
t = readtable(filename, opt );
t.Properties.VariableNames = {'X-AXIS', 'Y-AXIS'};
summary(t)
