Subject: Re: saving array

I tried, but it did not seem to work either...

irb(main):001:0> require "pstore"
true
irb(main):002:0> require "narray"
true
irb(main):003:0> array = NArray.int(2,2,2)
NArray.int(2,2,2): 
[ [ [ 0, 0 ], 
    [ 0, 0 ] ], 
  [ [ 0, 0 ], 
    [ 0, 0 ] ] ]
irb(main):004:0> db = PStore.new("myarray")
#<PStore:0x4020ab00 @transaction=false, @abort=false, @filename="myarray">
irb(main):005:0> db.transaction do
irb(main):006:1* db["data"] = array
irb(main):007:1> end
TypeError: can't dump NArray
