I am looking for equivalent of Matlab's expm() function in python. Can someone help me? Here is the Matlab explanation for the expm() function.

Thank you

I think the python equivalent is scipy.linalg.expm

See scipy documentation: https://docs.scipy.org/doc/scipy/reference/generated/scipy.linalg.expm.html

The following code replicates the Matlab example given in your link to the documentation.

import numpy as np
from scipy.linalg import expm

A = np.array([[1, 1, 0], [0, 0, 2], [0, 0, -1]])

expm(A)

Out[3]: 
array([[2.71828183, 1.71828183, 1.08616127],
       [0.        , 1.        , 1.26424112],
       [0.        , 0.        , 0.36787944]])
