# Matrix norm Calculator

## Calculates the L1 norm, the Euclidean (L2) norm and the Maximum(L infinity) norm of a matrix. | |||

Matrix norm

[1-1] /1 | Disp-Num |

- Bug report
- The text definition of the L2 norm is incorrect. The calculated result is correct though.

Is says it''s the maximum eigenvalue of A, that is lambda_max(A).

Instead it should say that it''s the largest spectral radius, that is sigma_max(A).

Equivalently that''s the largest eigenvalue of A^T.A (or A^* A for complex matrices).

See e.g. https://en.wikipedia.org/wiki/Matrix_norm - from Keisan
- Thank you for your advice.

We have fixed it.
