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
