That means, Vector for input values x:. In the latter case, read the answer. Vote for difficulty :.

In mathematics , especially in linear algebra and matrix theory , the vectorization of a matrix is a linear transformation which converts the matrix into a vector. The connection between the vectorization of A and the vectorization of its transpose is given by the commutation matrix. The vectorization is frequently used together with the Kronecker product to express matrix multiplication as a linear transformation on matrices. More generally, it has been shown that vectorization is a self-adjunction in the monoidal closed structure of any category of matrices. The matrix vectorization operation can be written in terms of a linear sum. Multiplication of X by e i extracts the i -th column, while multiplication by B i puts it into the desired position in the final vector.

Help Center Help Center. Vector creation, array subscripting, and for -loop iteration. It can create vectors, subscript arrays, and specify for iterations. These syntaxes enable operator overloading for classes. A :,n , A m,: , A : , and A j:k are common indexing expressions for a matrix A that contain a colon. When you use a colon as a subscript in an indexing expression, such as A :,n , it acts as shorthand to include all subscripts in a particular array dimension.
