You could also try using bincount, (np.bincount(x, y.real) +
1j*np.bincount(x, y.imag)) / np.bincount(x)

It doesn't
ok... I think -0.0 is mathematically wrong but in a program it is true.
What I suspect is that if -0.0 doesn't affect on result (e.g., 2*(-0.0 + 2) or
(-0.0-2)*2 ) . If it does not affect results it would be good for me
Thanks

ceil rounds toward +inf (and floor towards -inf) -- this is exactly
what you want if you're doing what I think you are...(note that
round() rounds towards and away from

I have a system that transmits signals for an alphabet of M symbols
over and additive Gaussian noise channel. The receiver has a
1-d array of complex received values. I'd like to find the means
of the received values according to the symbol that was transmitted.
So transmit symbol indexes might

What about it? What were you expecting to get? What do you think is
wrong about the answer you did get?

thanks a lot
what about the following example:
>>>new_ceil(-0.24, 0.25)
-0.0
???
thanks in advance for the reply

Hello,
I am using ceil() and floor() function to get upper and lower value of some
numbers. Let's say:
import math
x1 = 0.35
y1 = 4.46
>>> math.ceil(x1)
1.0
>>> math.floor(y1)
4.0
The problem is that If I want to get upper and lower values for the certain
step, for example, step = 0.25, ceil(
