存储在列表中的矩阵的乘法
Multiplication of matrices stored in lists
我正在努力将列表乘以 Python 中的矩阵。
我有两个列表(weights
和 returns
),我需要将它们相乘为:weights*TRANSPOSE(returns)
.
代码中的权重和 Return 是如何定义的?
您或许可以执行以下操作:
#This sums the entries
matrixProduct = 0
for i in range(len(Weights)):
matrixProduct+= Weights[i]*Return[i]
#In case you meant to keep products of individual pairs of matrix entries (not sure from your notation):
matrixProduct = []
for i in range(len(Weights)):
matrixProduct.append(Weights[i]*Return[i])
