Concepts inThe Influence of the Compiler on the Cost of Mathematical Software—in Particular on the Cost of Triangular Factorization
In mathematics, factorization (also factorisation in British English) or factoring is the decomposition of an object into a product of other objects, or factors, which when multiplied together give the original. For example, the number 15 factors into primes as 3 × 5, and the polynomial x − 4 factors as (x − 2)(x + 2). In all cases, a product of simpler objects is obtained.
