t=0
abig= zeros((10000,150))
aa=[0 for i in range(150)]
print abig[0]
while 1:
aa=abig[t]
for k in range(150):
for i in range(150):
ppp=aa[k]+nk[k]*(1-iris[k][3]*aa[i]*iris[i][3]*kk[i][k])
aa[k]=ppp
if aa[k]<0:
aa[k]=0
if aa[k]>10:
aa[k]=10
print abig[0]
abig[t+1]=aa
t=t+1
sds=subtract(abig[t-1],abig[t])
if norm(sds)<0.0001:
break
print t
print aa
我的期望是将每个分配abig[t]
给 aa,然后用 aa 进行一些计算,然后将 aa 分配回去,abig[t+1]
然后得到这两者的减法。
但这是我的结果:

两者abig[0]
不一样。所以减法是0
。为什么?kk[]
和nk[]
以上有一些定义iris[]
。它们是否相关?
