What is RREF (Reduced Row Echelon Form)?
什么是 RREF（化简行阶梯形）？
RREF stands for Reduced Row Echelon Form. It's a unique matrix form where: The first non-zero element in each row (called the leading coefficient) is 1. Each column containing a leading 1 has zeros in all its other entries. Any rows consisting of all zeros are at the bottom of the matrix. Each leading 1 is in a column to the right of the leading 1 in the row above it.
RREF 代表化简行阶梯形。这是一种独特的矩阵形式，其中：每行中的第一个非零元素（称为主系数）为 1。每列中包含主 1 的所有其他条目为 0。所有全零的行都位于矩阵的底部。每个主 1 都位于其上方行中的主 1 右侧的列中。
