The operations of matrix addition and matrix multiplication are especially simple for diagonal matrices.
One can check that with the operations of matrix addition and matrix multiplication, this set satisfies the above ring axioms.
The set of all 2 x 2 matrices is also a ring, under matrix addition and matrix multiplication.
The y-parameters of the combined network are found by matrix addition of the two individual y-parameter matrices.
Each ballot can be transformed into this style of matrix, and then added to all other ballot matrices using matrix addition.
Matrix multiplication is distributive over matrix addition, though also not commutative.
In mathematics, matrix addition is the operation of adding two matrices by adding the corresponding entries together.
The usual matrix addition is defined for two matrices of the same dimensions.
It is defined using the Kronecker product and normal matrix addition.
Applying further simplification and basic rules of matrix addition we come up with the following:
