frobenius

---

function frobenius(A:RealMatrixLike, B:RealMatrixLike) -> RealScalarLike

Matrix-matrix Frobenius product.

• A Matrix $A$.
• B Matrix $B$.

Returns Result $\langle A, B \rangle_\mathrm{F} = \mathrm{Tr}(A^\top B) = \sum_{ij} A_{ij} B_{ij}$ as a scalar.

function frobenius(A:RealMatrixLike) -> RealScalarLike

Matrix Frobenius product.

• A Matrix $A$.

Returns Result $\langle A, A \rangle_\mathrm{F} = \mathrm{Tr}(A^\top A) = \sum_{ij} A_{ij}^2$ as a scalar.
