[Scilab-users] scilab 6.1 crashes when trying to load big matfile (loadmatfile)

[Stéphane Mottelet]

Hello Antoine,

I made a 4Gb file with Matlab:

 >> a=rand(645,645,645);
 >> b=rand(645,645,645);
 >> c={a,b};
 >> save("c.mat","-7.3","c")

and managed to load it successfully in Scilab:

--> loadmatfile("c.mat");

--> c
  c  =

   [645x645x645 constant]  [645x645x645 constant]

Maybe the structure I tried is too simple (just two hypermatrices in a 
cell) so please give us a representative failing example.

S.
