check_eye

Simple utility to verify matrix inverses

Asserts that

\[\mathbf{T}^{-1}\mathbf{T} = \mathbf{I}\]

param T

Matrix to test

type T

np.ndarray

param Tinv

Supposed matrix inverse

type Tinv

np.ndarray

param msg

Output error message if inverse check not satisfied

type msg

str

param eps

Error threshold (\(10^\varepsilon\))

type eps

float

raises AssertionError

if matrix inverse check is not satisfied
