find the cordinate in the array using index

suppose i have three array

A = 
       X         Y
     10.22     21.32
     21.54     28.31
     94.43     64.11
     55.33     82.43
     66.11     32.43
     82.43     21.54
     55.33     82.00
     93.22     12.32

in each XY coordinate contain one value which will be store in array B
one value with respect to that XY coordinates contains
B= 
   29
   43
   69
   1
   88
   66
   21
array contain index value of each XY coordinates
  C=

      1
      2
      3
      4
      5
      6
      7

now i wish to get XY coordinate of any one value of B through index value

let i have one value from array B is 88

ch=88

and now how i get the index value of the that ch value

and how to get the XY coordinate from A through index value.

Assuming that you want to use ‘B’ and ‘C’, this works:

Result = A(C(B == 88),:)

produces:

Result =

      66.11    32.43
