您能提供一些示例输入，以及您期望的输出类型吗？输入为B0=20000000#基站的带宽Rreq=10000000#所需速率P#max=20#最大分配功率nb#max#iter=1000 P#om[0,0]=2输出功率为P_om，单位为瓦特，速率为Rom bit/sOk，所以我一直在努力解决这个问题。我有一些问题：1。你能修正一下你的代码缩进吗？所有代码都缩进了一次。2.在你发布的代码的第124行，你写了

u0=u0-t（P\u max-P0）

你的意思是

u0=u0-t*（P\u max-P0）

？3.在第121行，您使用

Cm[b-1，m-1]

作为数组或2D张量，但是您没有初始化数组，只有

Cm（）

作为函数4。在第126行，您使用变量

Interf

，它在while循环之前计算过一次，并且永远不会再更新，对吗？至于指针，我会确保您的所有函数输出都是浮动的，并且没有整数的数值计算，因为

1/2

将为您提供

0

，依此类推。他们会四舍五入，然后一个微小的错误会导致到处都是零乘法。对于你的第二个问题，是的，我想写u0=u0-t*（P_max-P0）。对于第三个问题，Cm[b-1，m-1]是一个矩阵，我把函数Cm的结果放在一个列表Cm.append（Cm（Bs，Vo））中，因为结果应该是一个标量，对于Interf它是一个常数（float）
