How can I relate points of different matrices ?

matrix a,b and c size are (26,26) and i wanna relate points a(1,1) with b(1,1) and c(1,1) in a way that if i change the order of the points the point of matrix c matches with points of a and b.

If you know exactly what you want to switch, follow this example:

A=[1 1; 2 2; 3 3]

And you want to switch row 1 with row 3, you would use

A([1 3],:)=A([3 1],:)

And you can repeat the same operation for the other matrices.

Since you've already accepted, I'll just post this as a comment:

Depending on your application, it might make sense to store abc as a 26-by-26-by-3 array:

a = [11, 12; 21, 22; 31, 32];
b = a*10;
c = a*100;

abc = cat(3, a, b, c);
% swap, e.g.,  (1, 1) with (3, 1)
swap = abc(1, 1, :);
abc(1, 1, :) = abc(3, 2, :);
abc(3, 2, :) = swap;

Alternatively, you could create an object/classdef with a, b & c as members, and write a method such that whenever one updates the order, the others are synched, but that maybe more trouble than it's worth. A slightly simpler version would be to define a short function which takes in the three matrices and repeats the operation for you.

Ultimately, simply repeating the operation as Mahdi described might be easiest.
