Conditional Indexing Using Specific Numbers in A Column

I have the following 2156 x 11 matrix (A). I have attached the matrix. I want to use column 11 to get all rows between 5001's and 6001's and put them in another matrix (B). I also want to get all the rows between 5001's and 1001's and put them in another matrix (C).

Below is a truncated version of column 11:
