load text file with specific format

fid = fopen('YourFile.txt', 'r');
first4cell = textscan(fid, '%g', 4);
restcell = textscan(fid, '%g%g%', 'CollectOutput', 1);
fclose(fid);
first4 = first4cell{1};
rest = restcell{1};

now first4 will be a column vector containing the 4 leading values, and rest will be an N x 3 matrix containing the values from the remainder of the file.

What datatype would you want it stored before you send it? What format does the executable need the data to be in?

Walter,

I believe I have asked a wrong question:) In fact, i just need to pass the text file to the executable. I figure how to do it.

your answer helped me in another part, and i've a question: when I use your approach I got this error:(Error using textscanBadly formed format string.) I changed %g%g%g to %d%d%d and works fine but it doesn't display the floating number and if i used %d%d%f it displays only two columns. Thank you for help
