我目前有以下内容,但它不会遍历 i. 我不明白为什么它不起作用。Bwavelength 和吞吐量是列表。我似乎从 0 开始,但不会增加到 1。

ABconstant=[]

c=3e18
for i in range(0, ((len(Bwavelength))-1)):
    ABconstant1=(((3e18/((Bwavelength[i])**2))*throughput[i]))
    ABconstant.append(ABconstant1)
    i+=1
    a=Bwavelength[0]
    b=Bwavelength[-1]
    h=((b-a)/len(Bwavelength))
    ABflux = numpy.trapz(Bwavelength, ABconstant, h)
return ABflux

我得到的错误是:

Traceback (most recent call last):
  File "Rewrite17.11.2014.py", line 196, in <module>
    ABflux1 = ABconversion(Bwavelength, throughput)
  File "Rewrite17.11.2014.py", line 186, in ABconversion
    ABflux = numpy.trapz(Bwavelength, ABconstant, h)
  File "C:\Python27\lib\site-packages\numpy\lib\function_base.py, line 3234, in trapz
    ret = add.reduce(d * (y[slice1]+y[slice2]/2.0, axis)
ValueError: Operands could not be broadcast together with shapes (0,) (444,)

Bwavelength 和throughput 长度相等。

我不知道这实际上意味着什么,尽管已经查过了。

提前致谢。

循环可以用向量计算代替:

c=3e18
ABconstant = c / numpy.array(Bwavelength) ** 2 * throughput
ABflux = numpy.trapz(ABconstant, Bwavelength)
return ABflux
