Hi, I have a text file that is neatly divided into two columns separated by tab. I can read each column fine, but I want to read the first value on the first column and keep it for later processing. You can see the text file attached and thanks in advance for your help!

在 MATLAB Online 中打开

fscanf( fid, '%f', [1 1] )

will do the job if you just want the first value.
