Now, because of the way matrix multiplication works, if you augment A with the identity matrix and row-reduce, you'll transform [A\ |\ I] into [EA∣ EI]=[R\ |E]. So, one way to find U is to augment A with the identity matrix, row-reduce, then extract the right-hand matrix ...
>>[m n] = find(a==b);这里[m n]返回的是满足条件的元素的行索引和列索引。如果矩阵a中没有元素等于max，find函数将返回一个空矩阵，如Empty matrix: 0-by-1。如果find函数返回Empty matrix: 0-by-1，则表示矩阵a中不存在与max相等的元素。这可能是由于以下几种原因：矩阵a中没有最大值。
