Follow-up Comment #4, bug #45387 (project octave):

Confirmed here also, with netlib blas I get


octave:1> [nan, 1] * [0; 1]
ans = NaN
octave:2> [nan, 1; 0, 0] * [0; 1]
ans =

   1
   0



and with openBLAS I get


octave:1> [nan, 1] * [0; 1]
ans = NaN
octave:2> [nan, 1; 0, 0] * [0; 1]
ans =

   NaN
     0
