Regulär — hat in verschiedenen Bereichen der Mathematik verschiedene Bedeutungen: In der abstrakten Algebra heißt ein Element einer algebraischen Struktur mit einer zweistelligen Operation regulär, wenn es kürzbar ist. Eine Halbgruppe heißt regulär, wenn… … Deutsch Wikipedia
Matrix decoder — is an audio technology where a finite number of discrete audio channels (e.g., 2) are decoded into a larger number of channels on play back (e.g., 5). The channels are generally, but not always, arranged for transmission or recording by an… … Wikipedia
Regular Hadamard matrix — In mathematics a regular Hadamard matrix is a Hadamard matrix whose row and column sums are all equal. While the order of a Hadamard matrix must be 1, 2, or a multiple of 4, regular Hadamard matrices carry the further restriction that the order… … Wikipedia
Regular local ring — In commutative algebra, a regular local ring is a Noetherian local ring having the property that the minimal number of generators of its maximal ideal is exactly the same as its Krull dimension. The minimal number of generators of the maximal… … Wikipedia
Regular graph — In graph theory, a regular graph is a graph where each vertex has the same number of neighbors, i.e. every vertex has the same degree or valency. A regular graph with vertices of degree k is called a kregular graph or regular graph of degree… … Wikipedia

Matrix differential equation — A differential equation is a mathematical equation for an unknown function of one or several variables that relates the values of the function itself and of its derivatives of various orders. A matrix differential equation is one containing more… … Wikipedia
Matrix representation of conic sections — In mathematics, the matrix representation of conic sections is one way of studying a conic section, its axis, vertices, foci, tangents, and the relative position of a given point. We can also study conic sections whose axes aren t parallel to our … Wikipedia
