Answer 1

Use the textscan command and set the ',' as delimiter.

filename = %name of the file;
delimiter = {','};
startRow = 3;
fileID = fopen(filename,'r');
formatSpec = '%f%f[^\n\r]';
dataArray = textscan(fileID, formatSpec, 'Delimiter', delimiter, 'TextType','string', 'HeaderLines' ,startRow-1, 'ReturnOnError', false, 'EndOfLine','\r\n');
fclose(fileID);
