Details:
This bug is present in both 3.2.3 and 3.3.54+. I tried to execute the test
found in liboctave/CMatrix.cc
assert([1+i 2+i ; 3+i 4+i ] * [5+i ; 6+i], [15 + 14i ; 37 + 18i], 1e-14)
It fails, and the funny thing is:
[1+i 2+i] * [5+i ; 6+i]
ans = 15 + 14i %# OK
[3+i 4+i ] * [5+i ; 6+i]
ans = 37 + 18i %# OK
[1+i 2+i ; 3+i 4+i ] * [5+i ; 6+i]
ans =
17 + 11i
39 + 11i
Just plain wrong.
Regards
Pascal
