This article deals with some fundamental matrix features and the basic arithmetic operations.
Matrices can have arbitrary dimensions. In the context of robotics mainly 3-by-3 or 4-by-4 matrices are used. An example of a 3-by-3 matrix is:
![\mathbf{M}=\left[
\begin{array}{ccc}
a_{11} & a_{12} & a_{13}\\
a_{21} & a_{22} & a_{23}\\
a_{31} & a_{32} & a_{33}
\end{array}\right]](/wiki/robotics/images/math/1/f/2/1f29be7647766c2d6f89f2f2f0217819.png)
