I have data from a walking data collection. Each marker has two columns of data and 134 rows of data. I need to create a vector that corresponds to the time of each frame starting at 0. I am assuming this would need to be done with some of loop. If anyone could help that would be great.

The actual question is: "I need to create a vector that corresponds to the time of each frame starting at 0"

What about:

t = linspace(0, 133/120, 134)  % Yes: 133/120, not 134/120
t = 1×134
         0    0.0083    0.0167    0.0250    0.0333    0.0417    0.0500    0.0583    0.0667    0.0750    0.0833    0.0917    0.1000    0.1083    0.1167    0.1250    0.1333    0.1417    0.1500    0.1583    0.1667    0.1750    0.1833    0.1917    0.2000    0.2083    0.2167    0.2250    0.2333    0.2417
