MATLAB: How to compare a single row with remaining all rows of a matrix

homeworkMATLABno attempt

my input matrix is v=[1 2 3 4 5;3 4 7 8 9;6 4 8 7 9;3 4 7 8 9;3 2 9 8 4]; I am taking second row alone. I have to compare it with all the remaining rows. How to do it. Suggest me simple code which has few lines.

MATLAB: Data comparision in matlab

   A = [1 7;2 8;3 9;4 10;5 11;6 12];
   B = [2 8;1 6;4 9;3 9;6 12;8 1;0 15];
   lia = ismember(A,B,'rows');
   Anew = A(lia>0,:);

Anew contains the rows that are common.

MATLAB: Is it possible to extract the values with a vector of indices for each row without using the for statement from the matrix

see sub2ind()

A = [1, 2, 3; 4, 5, 6; 7, 8, 9; 10, 11, 12]; % reference matrix
b = [2; 1; 1; 3]; % index for each row that I want to extract
idx = sub2ind(size(A), 1:size(A,1), b.');
A(idx)

Result

>> A(idx)
ans =
     2     4     7    12
