segmenting a column

[shivas007]

Hi,
I'm a newbie learning matlab and im presently working on dataset segmenting. I have a frame, suppose by dimensions 6500x192(approx) and the sampling frequency 100MHz. I need to segment each column ( 1 thru 192) into a fixed size(like 2mm length each) segments. I segmented the dataset with respect to time(like 2microseconds) but im not able to figure out as how to segment it with respect to the length. If we find out the length of each column (in this frame it will be 6500), in what units should we denominate it.
As I said i just started learning Matlab and it will be a great help if anyone of you can help me.Thanks.

Whoever gave you the data should be the person to ask.

Source for dataset is internet and i guess im doing the same dat you have suggested me but just asking a sibling.

If there's no context, then why not pick an arbitrary number?
