Suppose matrix A is as follows:
A = [1;2;3;4;5];
And matrix B:
B = [1,43,23,45;4,23,64,21;2,43,23,11;3,43,21,88;5,34,23,76;7,31,23,23,88;8,34,65,34];
I want to find the matrix A in matrix B and construct matrix C:
C = [1,43,23,45;2,43,23,11;3,43,21,88;4,23,64,21;5,34,23,76];

Edit
[ii,jj]=ismember(A,B(:,1));
C=B(jj(ii),:)
