How to get constant d if I know all other variables? 如果我知道所有其他变量,如何获得常数d? I tried to use math.log1p but it keeps giving me "Casting complex values to real discards the imaginary part".
我尝试使用math.log1p,但是它一直给我“将复杂值投射为实数会丢弃虚部”。
I get p = 0.0656073874479-0.399102149653j
, it can be represented as formula above where N = 20000
, k = 1
. 我得到
p = 0.0656073874479-0.399102149653j
,它可以表示为上面的公式,其中N = 20000
, k = 1
。
I want to calculate what d is. 我想计算d是多少。
您应该使用cmath
来获取复杂对数的某些分支:
cmath.log(p)*N/(-2*cmath.pi*1j*k)
