[Octave-bug-tracker] [bug #61912] Slow performance of complex()

[Rik]

Follow-up Comment #4, bug #61912 (project octave):

Finally found a situation, vectors for both RE and IM parts, where complex is
faster.


N = 1e5;

val = rand (1e4, 1);

tic;
for i = 1 : N
  #z = complex (val, val); 
  z = val + 1i*val; 
endfor
bm = toc


Timings:
complex() : 2.5 seconds
multiply  : 3.3 seconds
