Definition:Simultaneous Linear Equations/Matrix Representation/Matrix of Coefficients

Definition

Consider the system of simultaneous linear equations can be expressed as:

$\ds \forall i \in \set {1, 2, \ldots, m} : \sum_{j \mathop = 1}^n \alpha_{i j} x_j = \beta_i$

expressed in matrix representation as:

$\mathbf A \mathbf x = \mathbf b$

The matrix $\mathbf A$ is known as the matrix of coeffficients of the system.

Also known as

A matrix of coefficients is also known as a coefficient matrix.
