Wait. That's a major change in behavior, and will result in some broken
code out here in user-land:
-->getversion
ans =
scilab-5.5.2
-->A = rand(3,3)
A =
0.0683740 0.7263507 0.2320748
0.5608486 0.1985144 0.2312237
0.6623569 0.5442573 0.2164633
-->A = A + []
A =
0.0683740 0.7263507 0.2320748
0.5608486 0.1985144 0.2312237
0.6623569 0.5442573 0.2164633
