For the error, you can debug by typing the following at the command line and running your code:

dbstop if error

When the error occurs, the program will pause at the offending line will all variables intact. You can then examine the variables to see why they are not what you expected. Maybe j is not a positive integer >= 2, or maybe you inadvertently created a variable with the name "abs" and v is not a positive integer. Etc.
