Printing just one column in text file in scientific notation
2 views (last 30 days)

I am creating a text file with two columns of data using the following scheme:
data = [a b]
datafile = sprintf('file_%s.txt',label);
fileID = fopen(datafile,'w');
fprintf(fileID,'%f %f\n',data');
fclose(fileID);
I want the first column to be just the regular numbers, but the second column has very small values, so I want those printed out in the text file in scientific notation. How would I apply scientific notation to just that column? So when I open the text file it looks something like this (numbers arbitrary):
110.51 1.2222e-13
111.50 1.3897e-13
112.49 1.2342e-14
113.48 8.8123e-15
Thanks!
