Hi. Can you open your csv file with a text editor and see which separator is used for the values: ' ,' or ' ;' ?

If you have MATLAB R2014a or later version you have "Import data" tab on main window under Home tab. Just click on that, browse to your desired file and click import. Thats it.

If you are using a new enough version of MATLAB (might require R2015b), then csvread() should work if you pass it parameters that tell it to skip the first line
Otherwise,
fid = fopen('YourFile.csv','rt');
datacell = textscan(fid, '%d%d%d%d', 'HeaderLines',1,'Delimiter',',','CollectData', 1);
fclose(fid);
now datacell{1} is your numeric matrix

Replace YourFile.csv with the actual name of your file.
