Help Needed with looping commands

I have two sets of column data (about 120 data points each), d(:,1) and c(:,2).
How do I use the 'for' and 'if' loop commands to evaluate the difference between each of the points in the variables (that is, say E = d - c) and then compare each of the outcome with an error value computed already to produce another column data of results less than the error benchmark.
Thank you.

Just use:
E = d(:,1)-c(:,2) ;
You need not to use a loop.

Thank you for the reply. Actually, I needed the program to output E and c values at any point/points of detection showing less than the error value.

You can do what I have shown above right? Do the comparison, get the logical indices and pick the points.
