Generate array which shows moves that Karel can and can't make

This function creates open_moves, a nx x ny x 4 array of TRUE/FALSE values indicating if Karel can move to each direction from a given position. For example, if Karel is in the bottom left corner, which is cell [1, 1], it can't go south or left, so we have both open_moves[1, 1, 3] and open_moves[1, 1, 4] set to FALSE. Depending on the existing walls it could move south or north, so open_moves[1, 1, 1] and open_moves[1, 1, 2] could be TRUE or FALSE.
