On Minimizing the Number of Multiplications Necessary for Matrix ...
WebDevelops an algorithm to multiply a ptimes2 matrix by a 2times n matrix in [(3 pn+max ( n, p))/2] multiplications without use of commutativity of matrix elements. The algorithm minimizes the number of multiplications for matrix multiplication without commutativity for the special cases p=1 or 2, n=1,2 ... and p=3, n=3. WebNote that addition and multiplication, as defined here, are both closed since dividing by m will always produce a remainder between 0 and m − 1. Note also that commutativity, associativity, and distributivity of these operations follow from the respective properties of ordinary addition and multiplication (for example, dividing α + β by m ... launched on market

Additionand multiplicationare commutative in most number systems, and, in particular, between natural numbers, integers, rational numbers, real numbersand … See more In mathematics, a binary operation is commutative if changing the order of the operands does not change the result. It is a fundamental property of many binary operations, and many mathematical proofs depend on it. Most … See more Records of the implicit use of the commutative property go back to ancient times. The Egyptians used the commutative property of multiplication to simplify computing products. Euclid is known to have assumed the commutative property of multiplication in … See more • A commutative semigroup is a set endowed with a total, associative and commutative operation. • If the operation additionally has an identity element, we have a commutative monoid • An abelian group, or commutative group is a group whose group … See more A binary operation $${\displaystyle *}$$ on a set S is called commutative if One says that x commutes with y or that x and y commute under See more Commutative operations • Addition and multiplication are commutative in most number systems, and, in particular, between See more In group and set theory, many algebraic structures are called commutative when certain operands satisfy the commutative property.
