Matrix addition
Notions of sums for matrices in linear algebra / From Wikipedia, the free encyclopedia
In mathematics, matrix addition is the operation of adding two matrices by adding the corresponding entries together.

For a vector, , adding two matrices would have the geometric effect of applying each matrix transformation separately onto
, then adding the transformed vectors.
However, there are other operations that could also be considered addition for matrices, such as the direct sum and the Kronecker sum.
