tuples' :: [Int] -> [[Int]]Source

"Tuples" fitting into a give shape. The order is lexicographic, that is,

 sort ts == ts where ts = tuples' shape

Example:

 tuples' [2,3] = 
   [[0,0],[0,1],[0,2],[0,3],[1,0],[1,1],[1,2],[1,3],[2,0],[2,1],[2,2],[2,3]]

tuples1' :: [Int] -> [[Int]]Source

positive "tuples" fitting into a give shape.

countTuples' :: [Int] -> IntegerSource

# = \prod_i (m_i + 1)

countTuples1' :: [Int] -> IntegerSource

# = \prod_i m_i
