How to find permutation cycle in matlab?

A=

     4     1     2     3

     1     2     3     4

     2     3     4     1

     3     4     1     2

I define a function

s4(i)=j for which i , j = 4

as in my case

s4(1)=1

s4(2)=4

s4(3)=3

s4(4)=2

and find permutation as; (1)(24)(3)

How can I find these cycles in matlab ?

No, sorry I want to find the position of a number in a matrix then I define a mapping and I want to write in a cycle as I explained in my example.
