Hello,
in the program I am currently working on, I sometimes get the following error
messsage:
python: gri_mmse_fir_interpolator_cc.cc:66: gr_complex
gri_mmse_fir_interpolator_cc::interpolate(const gr_complex*, float):
Zusicherung »imu >= 0« nicht erfüllt.
Abgebrochen
It seems like the assertion "imu >= 0" failed.
The strange thing is, that the message behaves completely non-deterministic.
e.g. When I start the program 4 times, on the first 3 runs I get the error
message and suddenly at the 4th try, it runs without an error.
The assertion comes from the following method, which is located in the
gri_mmse_fir_interpolator_cc.cc file.
gr_complex
gri_mmse_fir_interpolator_cc::interpolate (const gr_complex input[], float mu)
{
int imu = (int) rint (mu * NSTEPS);
assert (imu >= 0);
assert (imu <= NSTEPS);
gr_complex r = filters[imu]->filter (input);
return r;
}
Does anyone has an explanation for this behavior or for what "imu >= 0" stands
for?
Thanks for your help,
Daniel
