- scipy.sparse.linalg.expm(A)[source]¶
Compute the matrix exponential using Pade approximation.
Parameters: A : (M,M) array_like or sparse matrix
2D Array or Matrix (sparse or dense) to be exponentiated
Returns: expA : (M,M) ndarray
Matrix exponential of A
Notes
This is algorithm (6.1) which is a simplification of algorithm (5.1).
New in version 0.12.0.
