Recall elements inside the rows of a matrix based on a predefined array

Given the following matrix

M= [	58	116.4	78.5	72.5	163.6	60.4	100	66	117	65	55;
	58.3	123.1	89.8	87.4	167.7	61.3	100	66	117	65	55;
	58.2	123.1	78.3	80.4	152.3	61.3	100	66	117	65	55;
	58	125.4	84.5	80.1	169.2	61.6	100	66	117	65	55;
	58	105.3	86.5	84.5	220.8	63.8	100	66	117	65	55;
	58.4	100.8	77	66.1	172.5	54.3	100	66	117	65	55;
	58	116.4	94.3	91	199.5	65.6	100	66	117	65	55;
	58.1	116.4	113.3	7.1	166.9	60.8	100	66	117	65	55;
	58.3	103	72.9	56.4	212.7	60.6	100	66	117	65	55;
	58	123.1	130.6	87.9	169.5	61.1	100	66	117	65	55;
	58	98.6	76.1	65.1	154.2	60	100	66	117	65	55;
	58	118.7	81.2	72.5	170.5	60.8	100	66	117	65	55;
	58	103	83.1	65.1	154.2	60	100	66	117	65	55;
	58.1	105.3	70.2	66.1	148.1	59.5	100	66	117	65	55;
	58	118.7	81.2	72.5	169.5	60.8	100	66	117	65	55]

I want to recall the elements in the rows based on a vector

V= [1 3 4 5 6 7 3 2 1 ]

So in this case the new Matrix A will have as first raw the first row of M, as second raw the 3rd row of M, as third raw the 4th row of M, as fourth row the fifth row of M and so on.

Every number inside V recall the specified row of M, creating the new matrix A

A =  [58	116.4	78.5	72.5	163.6	60.4	100	66	117	65	55;
      58.2	123.1	78.3	80.4	152.3	61.3	100	66	117	65	55;
      58	125.4	84.5	80.1	169.2	61.6	100	66	117	65	55;
      58	105.3	86.5	84.5	220.8	63.8	100	66	117	65	55;
      and so on
      

The number of raw of A will be equal to the length of the vector V, that could be longer than the one writted above

A = M(V,:);
