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.

Quite often, the reason why code has been written in a for loop is to compute values from 'nearby' ones. The function bsxfun can often be used to do this in a more succinct fashion. For example, assume that you wish to perform a columnwise operation on the matrix B , subtracting the mean of each column from it:. By using bsxfun , one can do the same job neatly and easily in just a single line:. Here, minus is a function handle opens new window to the minus opens new window operator - and will be applied between elements of the two matrices B and mean B. Other function handles, even user-defined ones, are possible as well. Another option would be to replicate v with repmat do not do this either :.
