- cupyx.scipy.linalg.expm(a)[source]#
Compute the matrix exponential.
- Parameters
a (ndarray, 2D) –
- Return type
matrix exponential of a
Notes
Uses (a simplified) version of Algorithm 2.3 of 1: a [13 / 13] Pade approximant with scaling and squaring.
Simplifications:
we always use a [13/13] approximate
no matrix balancing
