Hi all, The output of io.write_array is somehow strange especially when the imaginary part is negative. -3.840747834305893e-01+j3.251446106553843e+00 -3.840747834305893e-01-j-3.251446106553843e+00 -1.023995414172234e+00+j4.358924376676102e+00 -1.023995414172234e+00-j-4.358924376676102e+00 Any suggestion ?
