How can I fetch data from one matrix into another matrix?

I have matrix A and B.

when

A=

4

1

2

1

B=

1 100 200

2 300 400

3 500 600

4 700 800

5 900 1000

and then I would like to make matrix C.

C=

4 700 800

1 100 200

2 300 400

1 100 200

I would like to use A as a base and then sort data form B by using first column of B.

A= [4
1
2
1] ; 
B= [1        100        200
2        300        400
3        500        600
4        700        800
5        900        1000] ; 

[idx,ia] = ismember(B(:,1),A) ;
C = B(idx,:) 

C = 

     1   100   200
     2   300   400
     4   700   800

Sorry, I have tried this, but matrix C show me like a boolean value.
