借助**Numpy matrix.cumsum()**方法，我们能够找到给定矩阵的cumulative sum，并以一维矩阵的形式给出输出。
语法:
matrix.cumsum()返回: 返回矩阵累计和
示例#1 :
在这个示例中，我们可以看到，借助matrix.cumsum()方法，我们能够找到给定数组的累积和。
# import the important module in python
import numpy as np
# make matrix with numpy
gfg = np.matrix('[6, 2, 3]')
# applying matrix.cumsum() method
geeks = gfg.cumsum()
print(geeks)
Output:
[[ 6 8 11]]
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.cumsum() method
geeks = gfg.cumsum()
print(geeks)
Output:
[[ 1 3 6 10 15 21]]
