Details:

Two example scripts for computation of the Glover-Macfarlane H infinity
controller for a 3x3 (input-output) system (G)are are attached. For the exact
same system the script in file1.m fails while it succeeds with the script in
file2.m. The major difference appears the way the system G (and Wi) are
defined.
With file1.m the error report is 
"The X-Riccatti equation is not solved sucessfully"
"memory exhausted or requested size too large for range of Octave's index type
-- try to return to prompt"
