The application of calculation rules and methods involving matrices.
Matrix calculation is a branch of linear algebra.
Example
This is an example of matrix addition :
\(\begin{pmatrix}
4 & 6\\
2 & 3
\end{pmatrix} + \begin{pmatrix}
1 & 7\\
5 & 8
\end{pmatrix} = \begin{pmatrix}
4 + 1 & 6 + 7\\
2+5 & 3 + 8
\end{pmatrix} = \begin{pmatrix}
5 & 13\\
7 & 11
\end{pmatrix}\)
