将向量分配给矩阵的最后一行:MATLAB

Question

我想用向量替换矩阵的最后一行.

例如,我执行了以下操作并显示错误:

L = [1 2 3
     4 5 6
     4 6 7]

J = [1 4 6]

K = L(end,:)=J
K == find(L(:,end)=J)
                  ?
Error: The expression to the left of the equals sign is not a valid target for an assignment

我尝试了不同的代码但最终得到了

K = find(L(:,end)==J)    
ans = 9

---

我想要的结果是

K = [1 2 3
     4 5 6
     1 4 6] % This last row is now equal to J

任何帮助,将不胜感激.

您可以通过复制来轻松完成L.然后替换它:

K = L;
K(end, :) = J;

预期的结果是K.
