Edit note: 12/31 Revised RandIntV unique parameter to be type natural rather than boolean.
I am looking at getting these into the 2013.12 or 2014.01 release. @Trond, I cannot access your google code repository. I have written my own versions. What has me perplexed is how to handle generating a vector vs. a unique vector result.
My current RandIntV is:
impure function RandIntV (Min, Max : integer ; Unique : natural ; Size : natural) return integer_vector is variable result : integer_vector(1 to Size) ; begin -- if Unique = 0, it is more efficient to call RandIntV(Min, Max, Size) for i in result'range loop result(i) := RandInt(Min, Max, result(maximum(1, 1 + i - Unique) to Size)) ; end loop ; return result ; end function RandIntV ;
What bothers me is should it be one function with a parameter (perhaps optional) or should it be two separate functions, like RandIntV and RandIntVU (for unique). Not really liking either one.
The problem as I see is that we need these for (min,max), (min,max,exclude), (vector) and (vector, exclude):
impure function RandIntV (Min, Max : integer; Size : natural) return integer_vector ; impure function RandIntV (Min, Max : integer; Unique : natural; Size : natural) return integer_vector ; impure function RandRealV (Min, Max : real; Size : natural) return real_vector ; impure function RandIntV (Min, Max : integer; Exclude : integer_vector ; Size : natural) return integer_vector ; impure function RandIntV (Min, Max : integer; Exclude : integer_vector ; Unique : natural; Size : natural) return integer_vector ; -- no excludes for real vectors impure function RandIntV (A : integer_vector ; Size : natural) return integer_vector ; impure function RandIntV (A : integer_vector ; Unique : natural; Size : natural) return integer_vector ; impure function RandRealV (A : real_vector ; Size : natural) return real_vector ; impure function RandIntV (A : integer_vector ; Exclude: integer_vector ; Size : natural) return integer_vector ; impure function RandIntV (A : integer_vector ; Exclude: integer_vector ; Unique : natural; Size : natural) return integer_vector ; -- no excludes for real vectors
Any input appreciated.
