For my dissertation, my data is in a .csv file format, yet I've tried using this code to read in data. I don't understand what is going wrong. Matlab says there is a problem with the usage line, but what? The other I have done is put the name of the file. Could anyone solve my simple problem.
if (nargin ~= 1 ) usage(); end
fd = fopen(fname,'data.csv');
if (fd == -1)
msg = sprintf('File %s not opened\n',fname);
