The term matrix occurs equally in mathematics, data science, graphical representation, storage and switching technology.
In mathematics, a matrix is a two-dimensional arrangement of numbers listed in any number of columns and rows. The numbers are uniquely identified by specifying the row and column.
In computer graphics, displays and printers, a matrix contains pixels or dots from which, divided into rows and columns, the display or printed image is formed. The pattern of the pixels is determined by the position and allocation of the individual elements. In this context, reference should be made to the matrix printer.
- In switching and audio technology, it is a matter of distributing the signals. Here, the matrix is formed by a number of input and output lines that can be interconnected at the crossover points. Switching matrices are implemented in crossbar distributors.
