Hello,
I have a problem loading a text file that has format like this:
20
65
33
500
12 34 3.99
14 20 6.09
12 31 2.90
I have tried different functions e.g(import data,open, load,textscan ... ), none of them works. I need to use the above format as it is.
any suggestions please.

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?
