Again, I think Brian explained this and quite accurately.

I named my file gonary.rb

contents
require "rubygems"
require "narray"

ary1 = NArray.sfloat(3,4)
puts ary1.inspect
----------------------------
Results
----------------------------
<MANISH.local:jes> [09-03 07:03] 0 503:3  (0.16 Mb) ? ~/dev/noodle
! ruby gonary.rb
NArray.sfloat(3,4):
[ [ 0.0, 0.0, 0.0 ],
  [ 0.0, 0.0, 0.0 ],
  [ 0.0, 0.0, 0.0 ],
  [ 0.0, 0.0, 0.0 ] ]


See??

Cheers mate,

@Savard. This works if working through irb.

If I put the script in a .rb file "narray.rb", I get the following:


C:\Users\Abder-Rahman\Desktop\Research>ruby narray.rb
./narray.rb:2: uninitialized constant NArray (NameError)
        from narray.rb:1:in `require'
        from narray.rb:1

Why is that? Why cannot I get it running as throigh irb?

Of I insert

require "rubygems", I get the following:


C:\Users\Abder-Rahman\Desktop\Research>ruby narray.rb
./narray.rb:3: uninitialized constant NArray (NameError)
        from
C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`gem_original_require'
        from
C:/Ruby187/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in
`require'
        from narray.rb:2
