I have a structure of array of size 1x3 containing x and y coordinates as follows.
4 8
20 24
5 15
I want to shift the third row to first one. later 2nd one to first row. How to do it by using circshift?

You should experiment with it, and see what results you get.
Refer to the documentation for more information and examples.

A 1x3 array of structures:
S = struct('x',{4 20 5},'y',{8 24 15})
S.x
S.y
1. Shift the third element to first one using circshift:
S = circshift(S,1);
S.x
S.y
2. Later 2nd one to first element using circshift:
S = circshift(S,-1);
S.x
S.y

% Shift rows up by one position, making the third row the first
A_shifted = circshift(A, -1);
where A is your matrix/array.

Me, first time using circshift(). So, I'm not entirely sure about your intention. Are you suggesting to swap the 3rd row with the 1st row? And then, do you want to swap the 2nd row with the newly positioned 1st row?
Please clarify if my understanding is correct.
A = [ 4 8 % 1st row
20 24 % 2nd row
5 15]; % 3rd row
A([1,3],:) = circshift(A([1,3],:), 1)
A([1,2],:) = circshift(A([1,2],:), 1)

A structure of arrays:
S = struct('x',[4;20;5],'y',[8;24;15])
S.x,S.y
1. Shift the third row to first one using circshift:
S = structfun(@(v)circshift(v,1),S,'uni',0);
S.x,S.y
2. Later 2nd one to first row using circshift:
S = structfun(@(v)circshift(v,-1),S,'uni',0);
S.x,S.y
