Hello,

I am working on huges matrix and would like to know how octave manage them in 
memory:

With examples: a=rand(10000,10000) (or a huge matrix);
- b=a; # will it copy in memory or just make a reference?
- c.toto=a ; # will it copy in memory or just make a reference?
- d=reshape(a,....) # will it copy in memory or just make a reference?
- f=a(:) # will it copy in memory or just make a reference?
- g=a'; # will it copy in memory or just make a reference?
- the same in a function?


By the way , whos doesen't seems to show something related here. 

Thanks for all your work and see you...

Etienne de Foras
