With the help of Numpy matrix.take() method, we can select the elements from a given matrix by passing the parameter as index value of that element. It will return a matrix having one dimension. Remember it will work for one axis at a time.
Syntax :
matrix.take(index, axis)
Return : Return matrix of selected indexes
Example #1 :
In this example we can see that by selecting one index we get only one value in a matrix by using matrix.take() method.
# import the important module in python import numpy as np # make matrix with numpy gfg = np.matrix('[4, 1, 12, 3, 4, 6, 7]') # applying matrix.take() method geek = gfg.take(2) print(geek) |
Output:
[[12]]
Example #2 :
# import the important module in python import numpy as np # make matrix with numpy gfg = np.matrix('[4, 1, 9; 12, 3, 1; 4, 5, 6]') # applying matrix.take() method geek = gfg.take(0, 1) print(geek) |
Output:
[[ 4 12 4]]
