Python | Numpy matrix.cumsum()

With the help of Numpy matrix.cumsum() method, we are able to find a cumulative sum of a given matrix and gives output as one dimensional matrix.

Syntax : matrix.cumsum()

Return : Return cumulative sum of matrix

Example #1 :
In this example we can see that with the help of matrix.cumsum() method we are able to find the cumulative sum of a given array.

# 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]]

Example #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]]
