scipy.sparse.linalg._matfuncs:_ExpmPadeHelper
source: build-install/usr/lib/python3.14/site-packages/scipy/sparse/linalg/_matfuncs.py:336
Signature
class _ExpmPadeHelper(A, structure = None, use_exact_onenorm = False)Members
Summary
Help lazily evaluate a matrix exponential.
Extended Summary
The idea is to not do more work than we need for high expm precision, so we lazily compute matrix powers and store or precompute other properties of the matrix.
