[Octave-bug-tracker] [bug #32120] complex times complex failure

[Michael C. Grant]

Follow-up Comment #4, bug #32120 (project octave):

Can we consider re-opening this? I'm seeing a bug on this very test of
CMatrix.cc when building gui-release on the Mac using the native BLAS. Now, it
could very well be that the bug lies in the BLAS. But I would suggest that
this particular build case is important enough that we should figure out why
it is happening and attempt to work around it.

>> (1+i)*(4+i)+(2+i)*(5+i)+(3+i)*(6+i)
ans =  29 + 21i
>> x = [1+i 2+i 3+i]
x =

   1 + 1i   2 + 1i   3 + 1i

>> y = [ 4+i ; 5+i ; 6+i]
y =

   4 + 1i
   5 + 1i
   6 + 1i

>> x*y
ans =  6.9263e-310 + 6.9263e-310i
>> sum(x.'.*y)
ans =  29 + 21i
