Matlab: read only header line from a .csv-file

 Assume there's a myfile.csv with variable names in the first row and decimal numbers in the following ones. In Matlab I'd like to read the header line and the decimal numbers separately. So far, I've been doing the following to extract the header line: 

 

 fid = fopen('myfile.csv');
a = textscan(fid,'%s','Delimiter','\n');
b = a{1,1};
fclose(fid);
c = textscan(b,'%s','Delimiter',',');
d = c{1}

Then, I use the csvread command to extract the numerical part of the file. But there should be a (much) easier way to do it! First, I don't want to read the whole file (as with a = textscan(fid,'%s','Delimiter','\n');) to extract only the first line. Second, it looks wrong to use 7 lines of code to do it - can it be done with less?

I'd be thankful for any constructive suggestions.

Answers:Open the file with fopen, read the header line with textscan, read the decimal numbers with fscanf, and call fclose in the end - only 4 lines in total :) Example input file:
