function

`scipy.sparse.linalg._matfuncs:_ExpmPadeHelper.init`

source: build-install/usr/lib/python3.14/site-packages/scipy/sparse/linalg/_matfuncs.py:346

Signature

def __init__(self, A, structure = None, use_exact_onenorm = False)

Summary

Initialize the object.

Parameters

A : a dense or sparse square numpy matrix or ndarray: The matrix to be exponentiated.
structure : str, optional: A string describing the structure of matrix A. Only upper_triangular is currently supported.
use_exact_onenorm : bool, optional: If True then only the exact one-norm of matrix powers and products will be used. Otherwise, the one-norm of powers and products may initially be estimated.
