How to use the command "polyfit" to find the velocity ?

Hi !

With some datas imported I have to compute the velocity with the "polyfit" command, but I don't know what to do. I have to do that 6 times : 3 times with 6000x1 columns and 3 times with 5689x1 columns.

thanks in advance for your help !

Your description is a little vague, so some more details wills help. Also have a look here... Help With Homework

The first questions you need to think about are:

1) What are your data?

2) How do your data relate to velocity

3) How can you use polyfit to estimate that relation (try "doc polyfit" in the command window to get more info)
