Stop using negative numbers to index an array, like -1 in the following

 dompol1(-1,:)

It doesn't correspond to any array location.

MATLAB: It is showing the error ‘arrays indices must be positive integers or logical values’. The code and the pic of error attached with this question. thank you.

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.
