Matrix of factors : maple_ifactors

maple_ifactors has an integer n (or a list of integers) as parameter.
maple_ifactors decomposes the integer (or the integers of the list) into prime factors, but the output follows the Maple syntax :
it is a list with +1 or -1 (for the sign) and a matrix with 2 columns and where the lines are the prime factors and their multiplicity (or a list of lists...).
