coefficient. n. 1. (Mathematics) maths. a. a numerical or constant factor in an algebraic term: the coefficient of the term 3xyz is 3. b. the product of all the factors of a term excluding one or more specified variables: the coefficient of x in 3axyz is 3ayz.
The coefficient matrix is a matrix comprised of the coefficients of the variables. which is written such that each row represents one equation and each column contains the. coefficients for the same variable in each equation. The constant matrix is the solution to each of the. equations written in a single column and in the same order as the rows of the coefficient matrix. The augmented matrix is the coefficient matrix with the constant matrix as the last column.
