我的矩阵有重复数字的行.我想找到那些行并用虚拟行替换它们,以便保持矩阵的行数不变.

Dummy_row = [1 2 3]

(5x3)矩阵A.

A = [2 3 6;
     4 7 4;
     8 7 2;
     1 3 1;
     7 8 2]

(5x3)Matrix new_A

new_A = [2 3 6;
         1 2 3;
         8 7 2;
         1 2 3;
         7 8 2]

我尝试了以下删除了重复数字的行.

y = [1 2 3]
w = sort(A,2)
v = all(diff(t,1,2)~=0|w(:,1:2)==0,2)  %  When v is zero, the row has repeated numbers
z = A(w,:)

你能帮忙吗？
