If you post the file, or at least the first 20 lines or so, it would be easier to say which command is best to use. Generally, the command I would use is readtable, but I might edit the first lines to get a good header line before reading it. This is a good way to get an indication about how well readtable can pars your data:
opts = detectImportOptions('myCsvfile1.csv');
disp(opts)
For a csv with a single header line:
% read everything into a table
t1 = readtable('myCsvfile1.csv');
% select the data you want
t1 = t1.Var3;
For a csv file with an extra header line before the variable name header:
t2 = readtable('myCsvfile2.csv', 'HeaderLines',1);
t2 = t2.Var3;
