What if my input that I want to reflect is not 2x2 matrix?

@Ahmed Mahmoud , the example in the link that Mohammad shared shows data that are not in a 2x2 matrix. Take some time to study the example. You'll see a 2x5 matrix containg 5 [X;Y] coordinates.

You can multiply the reflection matrix with 2xn matrix of x,y coordinates.
x = [0 1 2 3 4 5];
y = [0 1 2 3 4 5];
reflectionmatrix = [-1 0; 0 1];
rm = reflectionmatrix * [x;y];
rx = rm(1,:);
ry = rm(2,:);
