I have a two matrix
A=[ 1 2 3;
2 1 4;
1 3 2; ]
and
B=[1 2 3]
i want the output matrix like,
C =[1 2 3;
1 2 4;
1 2 3]
how to get this output. The matrix A is sorted according to the matrix B.
Thanks.

A is First matrix (3x3 matrix).
A=[ 1 2 3;
2 1 4;
1 3 2; ]
B is another matrix (1x3 Matrix) ie.,
B=[1 2 3]
Based on B I want to sort each row in Matrix A.
C is the output matrix (3x3 Matrix)
C =[1 2 3;
1 2 4;
1 2 3]
here each row is sorted according the matrix B.

sort(A,2)
gives the result but had nothing to do with B
maybe you want this
C=sort(A,2)
C=C(:,B)
