GAUSS Mathematical and Statistical System 7.0

• Files larger than 2Gb are now supported
  
• GAUSS 7.0 now supports multiple library paths
  
• Structure Pointers - Structures were a significant addition to the GAUSS Programming Language. Structure pointers allow you to avoid unnecessary data copying when passing structures in and out of procedures, making it possible to write faster programs than ever before. For example,
  
  
  struct myStructure d;
  d.x = rndn(1000,100);
  d = myProc(d);
  
  
  If myProc edits any members of d, then myProc will first make a local copy of it. The return from myProc is then copied back to d when the procedure ends. Using structure pointers, you could define myProc to return 0 arguments and call myProc as follows:
  
  
  struct myStructure d;
  d.x = rndn(1000,100);
  myProc(&d);
  
  
  Passing a pointer to d into myProc causes the procedure to modify d directly rather than making a copy of it.
