简化列阶梯形矩阵 或 簡約行梯形式矩陣 (reduced row echelon form),也称作 行规范形矩阵 (row canonical form),如果满足额外的条件: 每个首项系数是1,且是其所在列的唯一的非零元素。 例如: 注意,这并不意味着简化列阶梯形矩阵的左部总是单位阵。 例如,如下的矩阵是简化行阶梯形矩阵: 因为第3列并不包含任何列的首项系数。 通过有限步的 行初等变换,任何矩阵可以变换为行阶梯形矩阵。 由于行初等变换保持了矩阵的 行空间,因此行阶梯形矩阵的行空间与 …
Row echelon form - Wikipedia
In linear algebra, a matrix is in row echelon form if it can be obtained as the result of Gaussian elimination. Every matrix can be put in row echelon form by applying a sequence of elementary row operations.
Echelon Form of a Matrix - stattrek.com
This lesson introduces the concept of an echelon matrix. Echelon matrices come in two forms: the row echelon form (ref) and the reduced row echelon form (rref). A matrix is in row echelon form (ref) when it satisfies the following conditions. The first non-zero element in each row, called the leading entry, is 1.
行阶梯形矩阵 - 百度百科
行阶梯形矩阵(Row-Echelon Form),是指 线性代数 中的某一类特定形式的 矩阵。 [1] 的矩阵称为行阶梯形矩阵,简称 阶梯型矩阵。 其特点为:每个阶梯只有一行;元素不全为零的行(非零行)的第一个非零元素所在列的下标随着行标的增大而严格增大(列标一定不小于行标);元素全为零的行(如果有的话)必在矩阵的最下面几行。 [1] 均为阶梯形矩阵。 [1] 在阶梯形矩阵中,若非零行的第一个非零元素全是1,且非零行的第一个元素1所在列的其余元素全为零,就称该矩阵为 …

Reduced Row Echelon Form (RREF) Calculator - eMathHelp
What Is Reduced Row Echelon Form? The Reduced Row Echelon Form (RREF) is an important concept in linear algebra. When a matrix is in RREF, it allows for a straightforward interpretation of the solution of the system of linear equations. Here's a more detailed explanation using an example. Consider the following system of three linear equations:
