What are the steps to calculate RREF?
计算 RREF 的步骤是什么？
The process to calculate RREF involves these key steps: 1. Start with the leftmost non-zero column as a pivot column. 2. Select the pivot element (topmost non-zero element in the pivot column). 3. Use row operations to make the pivot element 1 and all other entries in its column 0. 4. Repeat steps 1-3 for the next column to the right, ignoring rows above the current pivot row. 5. Continue until all pivot columns are processed.
计算 RREF 的过程包括以下关键步骤：1. 从最左侧的非零列开始作为主元列。2. 选择主元元素（主元列中的最上面的非零元素）。3. 使用行操作将主元元素变为 1，并将其列中的所有其他条目变为 0。4. 对右侧的下一个列重复步骤 1-3，忽略当前主元行上方的行。5. 继续处理所有主元列。
