In mathematics, a [[wp:matrix (mathematics)|matrix]] is a rectangular arrangement of scalars. An ''n'' × ''m'' matrix contains ''n'' rows and ''m'' columns. This example is a 3 × 4 matrix:
<math>M = \begin{bmatrix} 2 & 0 & -5 & -1 \\ -3 & -2 & -4 & 7 \\ -1 & -3 & 0 & -6 \end{bmatrix}</math>
Many computer languages can handle matrices. Tasks in this category create matrices, or do mathematics with matrices.
