numpy.einsum() Method

In NumPy, we can find Einstein’s summation convention of two given multidimensional arrays with the help of numpy.einsum(). We will pass two arrays as a parameter and it will return the Einstein’s summation convention.

Syntax: numpy.einsum()

Parameter: Two arrays.

Return : It will return the Einstein’s summation convention.

Example 1:

Output:

[1 2 3]
[4 5 6]
32

Example 2:

 Output:

[[0 1 2]
 [3 4 5]
 [6 7 8]]
[[10 11 12]
 [13 14 15]
 [16 17 18]]

[[ 45 48 51]
 [162 174 186]
 [279 300 321]]
