function outer(x:RealVectorLike, y:RealVectorLike) -> RealMatrixLike

Vector-vector outer product.

• x Vector $x$.
• y Vector $y$.

Returns Result $C = xy^\top$.

function outer(A:RealMatrixLike, B:RealMatrixLike) -> RealMatrixLike

Matrix-matrix outer product.

• A Matrix $A$.
• B Matrix $B$.

Returns Result $C = AB^\top$.

function outer(x:RealVectorLike) -> RealMatrixLike

Vector outer product.

• x Vector $x$.

Returns Result $B = xx^\top$.

function outer(A:RealMatrixLike) -> RealMatrixLike

Matrix outer product.

• A Matrix $A$.

Returns Result $B = AA^\top$.
