The word "matrix" refers to a situation or substance in which something develops or is contained. In mathematics, it specifically denotes a rectangular array of numbers, symbols, or expressions arranged in rows and columns, which can be used in various computations. In biology, a matrix can refer to the material or tissue in which more specialized structures are embedded, such as the extracellular matrix that provides structural and biochemical support to surrounding cells.
The word "matrix" comes from the Latin word "matrix," which means "womb" or "source," derived from "mater," meaning "mother." This reflects the idea of something being a foundational or nurturing environment for development.
