Hi all,

         Thank you very much in advance.

          I find the result of the block "complex to Arg" is same to the
result in matlab most of the time,while sometimes the results is different
from the result in matlab.

          For example,
         a=1.646236600879293e+03 + 8.043715071772031e+00i
          I use the command  atan2 or angle to calculate the result.
          It return 0.004886084452240.

          While i calculate the result using the gnuradio.
          It return 0.002944485750049.

          Can someone explain it?

          The version of gnuradio:3.7.5.
Best regards,
xd
