Topics related to "Matrix"

matrix
matrix in mathematics, a rectangular array of elements (e.g., numbers) considered as a single entity. A matrix is distinguished by the number of rows and columns it contains. The matrix is a 2×3 (read "2 by 3" ) matrix, because it contains 2 rows and 3 columns. A matrix having the same ... Read more
composite material
composite material or composite, any material made from at least two discrete substances, such as concrete. Many materials are produced as composites, such as the fiberglass -reinforced plastics used for automobile bodies and boat hulls, but the term usually is used to describe any of various ... Read more
cytoplasm
cytoplasm The material surrounding the nucleus of a cell. It consists of a matrix (see cytosol) in which the cell's organelles are suspended. The cytoplasm may be differentiated into dense outer ectoplasm, which is concerned primarily with cell movement, and less dense endoplasm, which contains most... Read more
Babbitt metal
Babbitt metal an antifriction metal first produced by Isaac Babbitt in 1839. In present-day usage the term is applied to a whole class of silver-white bearing metals, or "white metals." These alloys usually consist of relatively hard crystals embedded in a softer matrix, a structure important f... Read more
printer
printer computer output device that reproduces data on paper or another medium. Impact printers use a mechanical hammering device to produce each character. A formed character printer forces metal or plastic characters against an inked ribbon to produce a sharp image on paper; the characters ma... Read more
determinant
determinant a polynomial expression that is inherent in the entries of a square matrix . The size n of the square matrix, as determined from the number of entries in any row or column, is called the order of the determinant. If the entry in row i and column j is denoted as aij , then, for ... Read more
