Definition
A system of simultaneous linear equations:
- $\ds \forall i \in \set {1, 2, \ldots, m}: \sum_{j \mathop = 1}^n \alpha_{i j} x_j = \beta_i$
is referred to as homogeneous if and only if:
- $\forall i \in \set {1, 2, \ldots, m}: \beta_i = 0$
That is:
\(\ds \alpha_{1 1} x_1 + \alpha_{1 2} x_2 + \cdots + \alpha_{1 n} x_n\) | \(=\) | \(\ds 0\) | ||||||||||||
\(\ds \alpha_{2 1} x_1 + \alpha_{2 2} x_2 + \cdots + \alpha_{2 n} x_n\) | \(=\) | \(\ds 0\) | ||||||||||||
\(\ds \) | \(\cdots\) | \(\ds \) | ||||||||||||
\(\ds \alpha_{m 1} x_1 + \alpha_{m 2} x_2 + \cdots + \alpha_{m n} x_n\) | \(=\) | \(\ds 0\) |
