摘要
三对角线型行列式是线性代数中一种常见的具有特殊格式的行列式，通过举例的方式对此类行列式的计算进行探讨，由简单形式的行列式到元素复杂的行列式进行推导，并在行列式的元素满足一定条件的情形下，得到一般形式三对角线型行列式的计算方法及其计算公式。
Abstract
Tridiagonal determinant is a common and with special format determinant in the linear algebra, by the way of giving examples, discusses the computing method of this class determinant, and deduces it through the simple formal to the complex elements determinant. When the determinant elements satisfy a certain condition, obtains the computing method and computing formula of the general tridiagonal determi-nant.
