Somone can help me with unique and find function?

Hello everyone,

I have two matrix A and B and i wanna find the row equals in both matrix and remove the line on matrix B. I wanna safe on the vector the position the lines,How can i do it?

For example:

A = [1 2 6 3;

4 5 6 9;

7 7 7 6;

9 8 7 3];

B = [0 9 6 3;

3 5 1 9;

7 7 7 6;

9 8 9 9];

the row equals is row 3. So i wanna find the rows equal, that's row 3 and leave the matrix B this way:

B = [0 9 6 3;

3 5 1 9;

9 8 9 9];

vector = 3;

[lo,ix]= ismember(A,B,'rows')
B = B(~lo,:)
vector = ix(lo)

[madhan ravi]

ix = all(A == B, 2);
B = B(~ix, :)
vector = find(ix)
