借助**Numpy matrix.cumprod()**方法，我们能够找到给定矩阵的cumulative product，并以一维矩阵的形式给出输出。
语法:
matrix.cumprod()返回: 返回矩阵的累计乘积
示例#1 :
在这个示例中，我们可以看到借助于matrix.cumprod()方法，我们能够找到给定矩阵的累积积。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[6, 2, 3]')
# applying matrix.cumprod() method
geeks = gfg.cumprod()
print(geeks)
Output:
[[ 6 12 36]]
例 2 :
# import the important module in python
import numpy as np
# make a matrix with numpy
gfg = np.matrix('[1, 2, 3; 4, 5, 6]')
# applying matrix.cumprod() method
geeks = gfg.cumprod()
print(geeks)
Output:
[[ 1 2 6 24 120 720]]
