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 |
